The future of future-oriented cognition in non-humans: theory and the empirical case of the great apes

One of the most contested areas in the field of animal cognition is non-human future-oriented cognition. We critically examine key underlying assumptions in the debate, which is mainly preoccupied with certain dichotomous positions, the most prevalent being whether or not ‘real’ future orientation is uniquely human. We argue that future orientation is a theoretical construct threatening to lead research astray. Cognitive operations occur in the present moment and can be influenced only by prior causation and the environment, at the same time that most appear directed towards future outcomes. Regarding the current debate, future orientation becomes a question of where on various continua cognition becomes ‘truly’ future-oriented. We question both the assumption that episodic cognition is the most important process in future-oriented cognition and the assumption that future-oriented cognition is uniquely human. We review the studies on future-oriented cognition in the great apes to find little doubt that our closest relatives possess such ability. We conclude by urging that future-oriented cognition not be viewed as expression of some select set of skills. Instead, research into future-oriented cognition should be approached more like research into social and physical cognition.

Predicting the future is a challenging task for music education, requiring both retrospection, analysis of current events, and foresight. This article examines several predictions from 2001 and challenges music educators to consider factors that may influence the future of teaching music in society.     

Eurasian jays (Garrulus glandarius) overcome their current desires to anticipate two distinct future needs and plan for them appropriately

Western scrub-jays (Aphelocoma californica) have been shown to overcome present satiety to cache food they will desire in the future. Here, we show that another corvid, the Eurasian jay (Garrulus glandarius), can distinguish between two distinct future desires and plan for each appropriately, despite experiencing a conflicting current motivation. We argue that these data address the criticisms of previous work, and suggest a way in which associative learning processes and future-oriented cognition may combine to allow prospective behaviour.     

Can animals recall the past and plan for the future?

According to the 'mental time travel hypothesis' animals, unlike humans, cannot mentally travel backwards in time to recollect specific past events (episodic memory) or forwards to anticipate future needs (future planning). Until recently, there was little evidence in animals for either ability. Experiments on memory in food-caching birds, however, question this assumption by showing that western scrub-jays form integrated, flexible, trial-unique memories of what they hid, where and when. Moreover, these birds can adjust their caching behaviour in anticipation of future needs. We suggest that some animals have elements of both episodic-like memory and future planning.     

Mental time travel: animals anticipate the future

Recent behavioral experiments with scrub jays and nonhuman primates indicate they can anticipate and plan for future needs not currently experienced. Combined with accumulating evidence for episodic-like memory in animals, these studies suggest that some animals can mentally time travel into both the past and future.     

Mental time travel in animals: a challenging question

Humans have the ability to mentally recreate past events (using episodic memory) and imagine future events (by planning). The best evidence for such mental time travel is personal and thus subjective. For this reason, it is particularly difficult to study such behavior in animals. There is some indirect evidence, however, that animals have both episodic memory and the ability to plan for the future. When unexpectedly asked to do so, animals can report about their recent past experiences (episodic memory) and they also appear to be able to use the anticipation of a future event as the basis for a present action (planning). Thus, the ability to imagine past and future events may not be uniquely human.     

Explaining why larks are future-oriented and owls are present-oriented: Self-control mediates the chronotype–time perspective relationships

Recent studies provide evidence for the chronotype–time perspective relationships. Larks are more future-oriented and owls are more present-oriented. The present study expands this initial research by examining whether the associations are replicable with other time perspective measures, and whether self-control explains the observed relationships. Chronotype was assessed with the Morningness–Eveningness Questionnaire and the basic associations with the Zimbardo Time Perspective Inventory were replicated in a sample of 142 New Zealand students, but not with other measures. Self-control mediated the influence of morningness on both future time perspective and delay of gratification. Implications of the findings are discussed.     

Wild Minds: What People Think about Animal Thinking

ABSTRACT

The question of how nonhuman animals think is pervasive in the scientific and popular media, yet there is an apparent lack of concordance between findings from research in animal cognition and how this information emerges in popular discourse. The present study investigated the way people conceive of animal thinking, in order to inform the development of an exhibit on animal minds that will address this issue and foster a deeper connection between people and animals. This two-part, sequential study of perceptions of animal thinking used qualitative interviews of visitors to the New York Hall of Science and Staten Island Zoo to develop a quantitative, online consumer survey of American museum visitors. The results show that American museum visitors vary in their perceptions of animal thinking, but appear to be open to new ideas about how animals might think. Participants' responses to the interviews revealed they could easily recognize survival strategies in wild animals, but had reservations about discussions of empathy, deception, and awareness. In addition, animals kept as pets or companion animals in Western culture were commonly perceived to have higher cognitive capacities for thinking than food or other domestic animals. Participants' responses to the online consumer survey appeared to focus on an overall concept of animal thinking, rather than different cognitive dimensions. Although participants were generally neutral in their responses, demographic analysis revealed participants who had dogs and/or cats, a college education, or watched nature shows were more likely to support the belief that animals can think. Participants who had children at home were less likely to support this belief. Further research is needed to determine how different kinds of thought processes are understood by general audiences and how demographic factors might influence perceptions of animal thinking.     

Differential influence of asynchrony in early and late chronotypes on convergent thinking

Eveningness preference (late chronotype) was previously associated with different personality dimensions and thinking styles that were linked to creativity, suggesting that evening-type individuals tend to be more creative than the morning-types. Nevertheless, empirical data on the association between chronotype and creative performance is scarce and inconclusive. Moreover, cognitive processes related to creative thinking are influenced by other factors such as sleep and the time of testing. Therefore, our aim was to examine convergent and divergent thinking abilities in late and early chronotypes, taking into consideration the influence of asynchrony (optimal versus nonoptimal testing times) and sleep quality. We analyzed the data of 36 evening-type and 36 morning-type young, healthy adults who completed the Compound Remote Associates (CRAs) as a convergent and the Just suppose subtest of the Torrance Tests of Creative Thinking as a divergent thinking task within a time interval that did (n = 32) or did not (n = 40) overlap with their individually defined peak times. Chronotype was not directly associated with creative performance, but in case of the convergent thinking task an interaction between chronotype and asynchrony emerged. Late chronotypes who completed the test at subjectively nonoptimal times showed better performance than late chronotypes tested during their “peak” and early chronotypes tested at their peak or off-peak times. Although insomniac symptoms predicted lower scores in the convergent thinking task, the interaction between chronotype and asynchrony was independent of the effects of sleep quality or the general testing time. Divergent thinking was not predicted by chronotype, asynchrony or their interaction. Our findings indicate that asynchrony might have a beneficial influence on convergent thinking, especially in late chronotypes.     

The future‐like‐ours argument,animalism, and mereological universalism

Which metaphysical theories are involved—whether presupposed or implied—in Marquis’ future‐like‐ours (FLO) argument against abortion? Vogelstein has recently argued that the supporter of the FLO argument faces a problematic dilemma; in particular, Marquis, the main supporter of the argument, seems to have to either (a) abandon diachronic universalism (DU) or (b) acquiesce and declare that contraception is morally wrong. I argue that the premises of Marquis’ argument can be reasonably combined with a form of unrestricted composition and that the FLO argument is better viewed as including animalism, i.e., the thesis that we are animals.     

The effect of travel costs on the ideal free distribution in stickleback

The ideal free distribution (IFD) theory, which predicts that a population of individuals will match the distribution of a patchily distributed resource, is widely used in ecology to describe the spatial distribution of animals. While many studies have shown general support of its habitat matching prediction, others have described a systematic pattern of undermatching, where too many animals feed at patches with fewer resources, and too few animals feed in richer patches. These results have been attributed to deviations from several of the assumptions of the IFD. One possible variable, the cost of travelling between patches, has received little attention. Here, we investigated the impact on resource matching when travel costs were manipulated in a simple laboratory experiment involving two continuous input patches. This experiment allowed us to control for extraneous variables and decouple time costs from energetic costs of travel. Two experiments examined the impact of varying travel costs on movement rates between foraging patches and how these travel costs impact conformity to the IFD. Our data demonstrated that there was less movement between patches and greater discrepancies from the IFD predictions as the cost of travel increased.     

Starlings (Sturnus vulgaris) exploiting patches: response to long-term changes in travel time

In this paper we explore the way foraging animals integrateexperience over time. The marginal value theorem shows thatto maximize long-term gain rate, foragers should adjust patchexploitation to theaverage travel time for the habitat, andmany experiments do find a positive relationship between averagepatch exploitation and average interpatch travel time. Thisrelationship implies that animals use experience to determineforaging tactics but, by itself, does not imply that anythingbut the most recent experience (say, the time taken to findthe current patch) has an effect on behavior. We directly testedthe influence of events before the most recently experiencedtravel by examining adjustments in foraging behavior after stepwisechanges between two homogeneous environments, each with a singletravel distance. Using starlings (Sturnus vulgaris) in a closed-economylaboratory simulation of a patchy environment, we found thatduring periods of active foraging, the average number of preyper patch visit is in close agreement with that predicted forrate maximization. After changes in travel time, birds tookapproximately six full cycles of travel and patch use beforereaching a new asymptotic behavior. The pattern of adjustmentdid not vary with successive presentations of the environmentalchange. These results demonstrate that memory for more thanone travel episode is involved in the foraging decisions ofstarlings. We relate our results to apparently conflicting datafrom previous experiments and to models of memory and informationprocessing.     

Behavioral flexibility of vervet monkeys in response to climatic and social variability

Responses to environmental variability sheds light on how individuals are able to survive in a particular habitat and provides an indication of the scope and limits of its niche. To understand whether climate has a direct impact on activity, and determine whether vervet monkeys have the behavioral flexibility to respond to environmental change, we examined whether the amount of time spent resting and feeding in the nonmating and mating seasons were predicted by the thermal and energetic constraints of ambient temperature. Our results show that high temperatures during the nonmating season were associated with an increase in time spent resting, at the expense of feeding. Cold temperatures during the nonmating season were associated with an increase in time spent feeding, at the expense of resting. In contrast, both feeding and resting time during the mating season were independent of temperature, suggesting that animals were not adjusting their activity in relation to temperature during this period. Our data indicate that climate has a direct effect on animal activity, and that animals may be thermally and energetically compromised in the mating season. Our study animals appear to have the behavioral flexibility to tolerate current environmental variability. However, future climate change scenarios predict that the time an animal has available for behaviors critical for survival will be constrained by temperature. Further investigations, aimed at determining the degree of behavioral and physiological flexibility displayed by primates, are needed if we are to fully understand the consequences of environmental change on their distribution and survival.

Six ways in which a foraging predator may encounter options with different variances

We consider the idea that foraging animals seek to achieve a certain threshold intake of food per day rather than maximising mean energy intake. Earlier experiments and theoretical work have shown that under these conditions animals should respond to variance in reward. We identify six possible sources of such variance and produce models for five of them (the sixth is already solved). These models describe (1) whether to feed in habitats possessing small or large prey, (2) whether to feed on clumped or dispersed prey, (3) which prey items to eat, (4) the effects of misidentification of prey selection, (5) whether to feed singly or join a flock and (6) when to move between patches when the travel time between them is variable. The results are often radically different from those of traditional models and we discuss their biological significance.     

Circadian Preference and Thinking Styles: Implications for School Achievement

Research has shown that thinking styles could have an influence on academic achievement. Previous studies have described that evening types are usually right-thinkers who tend to be creative and intuitive, whereas morning types tend to be left-thinkers who prefer verbal and analytic strategies in processing information. However, these studies have been realized among undergraduates, who have more freedom to choose their time schedules according to their circadian preference than adolescents or adult workers. On other hand, the relationship between thinking styles and circadian preference has not been analyzed considering school achievement. The present study aims (1) to investigate the relationship between circadian preference, that is, behavioral differences in circadian rhythmic expression, and thinking styles, referring to the preference toward information processing typical of the right versus the left cerebral hemisphere; and (2) to test the implications for self-reported school achievement. A sample of 1134 preadolescents and adolescents (581 girls; mean?±?SD age: 12.1?±?1.47, range: 10–14?yrs) completed the Morningness-Eveningness Scale for Children (MESC) as measure of circadian preference (morning, neither, or evening types), the Hemispheric Preference Test (HPT), conceived as a tool to measure thinking styles (right-, balanced-, and left-thinkers), and self-reported school achievement. Results indicated a greater percentage of left-thinkers among morning types and a greater percentage of right-thinkers among evening types. No differences were found among balanced-thinkers and neither types. Morning types and left-thinkers reported the highest subjective level of achievement, followed by evening types and left-thinkers, and morning types and right-thinkers. Evening types and right-thinkers reported the lowest subjective level of achievement. Finally, multivariate regression analysis indicated that age, left hemisphere and morning preferences accounted for 14.2% of total variance on self-reported achievement.

Perception of Environmental Threat in the Shadow of War: The Effect of Future Orientation

People may express high concern for global warming or environmental degradation, but when forced to evaluate the severity of environmental threats in relation to other threats, environmental threats are pushed to the bottom of the list. The present study was based on the premise that prioritizing threats involves, inter alia, hierarchizing the threats according to their perceived temporal proximity and since environmental threats are perceived, relative to other threats, as more temporally distant, they rank low. Future orientation (FO) is an individual-difference variable that describes the tendency to take into account temporally distant considerations. We predicted that environmental threats would be evaluated as more severe by individuals who were more future-oriented. The strongest effect of FO was found to be on concern about global warming and environmental degradation. This indicated that environmental threats were perceived as temporally farthest and, not surprisingly, received the lowest priority. External security threat was a top-priority; its severity evaluation was uncorrelated to FO, indicating that it was perceived as temporally closest. These evaluations significantly affected environmental attitudes and behavior. The implications on promoting environmental behavior in the presence of ever-existing shorter-term existential threats are discussed.     

Are larks future-oriented and owls present-oriented? Age- and sex-related shifts in chronotype–time perspective associations

The chronotype (morningness/eveningness) relates to individual differences in circadian preferences. Time perspective (past, present, future) refers to the preference to rely on a particular temporal frame for decision-making processes and behavior. First evidence suggests that future time perspective is associated with greater morningness and present time perspective with greater eveningness. However, little is known about how chronotype–time perspective relationships may alter over the life span. This present study investigated links between chronotype and time perspective more thoroughly by taking age and sex into account as well. Seven hundred six participants aged between 17 and 74 completed German adaptations of the Morningness--Eveningness Questionnaire (MEQ) and Zimbardo Time Perspective Inventory (ZTPI). Controlling for age and sex, relationships between morningness and future time perspective as well as between eveningness and present time perspective were replicated. These findings were supported by significant associations between time perspective and midpoint of sleep. Future time perspective was linked to earlier midpoints of sleep, indicating an early chronotype. Present time perspective was associated with later midpoints of sleep, indicating a late chronotype. However, age and sex had an impact on the chronotype–time perspective relationships. In all age groups, male larks were more future-oriented and less present-oriented, male owls more present-oriented and less future-oriented. The same conclusion could be drawn for female adolescents and young adults. For female adults above 30, there was no interrelationship between morningness and future time perspective but between eveningness and past time perspective. Female adult owls were more present-oriented as well as more past-oriented. Female adult larks were less present-oriented and less past-oriented. Findings are discussed in the light of neuroendocrine and serotonergic functioning.     

The evolutionary origins of human patience: temporal preferences in chimpanzees, bonobos, and human adults

To make adaptive choices, individuals must sometimes exhibit patience, forgoing immediate benefits to acquire more valuable future rewards [1-3]. Although humans account for future consequences when making temporal decisions [4], many animal species wait only a few seconds for delayed benefits [5-10]. Current research thus suggests a phylogenetic gap between patient humans and impulsive, present-oriented animals [9, 11], a distinction with implications for our understanding of economic decision making [12] and the origins of human cooperation [13]. On the basis of a series of experimental results, we reject this conclusion. First, bonobos (Pan paniscus) and chimpanzees (Pan troglodytes) exhibit a degree of patience not seen in other animals tested thus far. Second, humans are less willing to wait for food rewards than are chimpanzees. Third, humans are more willing to wait for monetary rewards than for food, and show the highest degree of patience only in response to decisions about money involving low opportunity costs. These findings suggest that core components of the capacity for future-oriented decisions evolved before the human lineage diverged from apes. Moreover, the different levels of patience that humans exhibit might be driven by fundamental differences in the mechanisms representing biological versus abstract rewards.     

Plant behaviour and communication

Plant behaviours are defined as rapid morphological or physiological responses to events, relative to the lifetime of an individual. Since Darwin, biologists have been aware that plants behave but it has been an underappreciated phenomenon. The best studied plant behaviours involve foraging for light, nutrients, and water by placing organs where they can most efficiently harvest these resources. Plants also adjust many reproductive and defensive traits in response to environmental heterogeneity in space and time. Many plant behaviours rely on iterative active meristems that allow plants to rapidly transform into many different forms. Because of this modular construction, many plant responses are localized although the degree of integration within whole plants is not well understood. Plant behaviours have been characterized as simpler than those of animals. Recent findings challenge this notion by revealing high levels of sophistication previously thought to be within the sole domain of animal behaviour. Plants anticipate future conditions by accurately perceiving and responding to reliable environmental cues. Plants exhibit memory, altering their behaviours depending upon their previous experiences or the experiences of their parents. Plants communicate with other plants, herbivores and mutualists. They emit cues that cause predictable reactions in other organisms and respond to such cues themselves. Plants exhibit many of the same behaviours as animals even though they lack central nervous systems. Both plants and animals have faced spatially and temporally heterogeneous environments and both have evolved plastic response systems.
