Overview: Signal production and detection

Studies of signal production and detection are complicated by the diverse modalities used by animals, constraints of human signal perception, and limitations of a controlled laboratory environment. These complications can be addressed by creative approaches to studying anatomical adaptations for signal production and detection, innovative technology, and careful studies of signal production and detection in the field. These solutions should overcome the perceptual limitations of researchers as they explore Umwelten in other species.     

Macbeth,Throne of Blood,and the Idea of a Reflective Adaptation

Adaptations have varied relations to their source material, making it hard to formulate a general theory. Avoiding the attempt, we characterize a narrower, more unified class of reflective adaptations which communicate an active and sometimes critical relation to the source's framework. We identify the features of reflective adaptations which give them their distinctive interest. We show how these features are embodied in Akira Kurosawa's Throne of Blood, an adaptation with a radically shifted perspective on the relation between character and situation compared to its Shakespearean source. We identify some of the artistic choices through which this response to the source is conveyed, such choices being a characteristic feature of reflective adaptations.     

Adaptation, evolution, and religion

Neo-Darwinian theories of religion include both nonadaptationist and adaptationist versions. Nonadaptationist versions contend that the mental architecture of the brain is wired for religious thinking but that religious concepts have piggybacked on other cognitive adaptations, especially those for agency detection. Religious concepts are not evolved biological adaptations but rather by-products of more general cognitive structures that are adaptations. Adaptationist versions concentrate on the benefits provided by religion, such as increased social cohesion and the individual benefits that stem from it, such as better physical and mental health and greater longevity. After clarifying the meaning of the terms “adaptation” and “adaptationism,” this article presents four lines of evidence in favor of the adaptationist position: (1) in the ancestral environment the role of the shaman was nearly universal and was primarily devoted to the crucial human goals of curing illness and protecting and finding vital resources; (2) religion generally has positive effects on both physical and mental health; (3) religions tend to be pro-natalist and more religious people tend to leave more offspring than less religious or nonreligious people; (4) the major world religions that evolved in the first millennium BCE during a period of major social chaos and disruption emphasized an omnipotent, transcendent God of love and mercy who offered salvation in a heavenly afterlife and released individuals from earthly suffering. None of these facts demonstrate conclusively that cognitive modules specifically oriented to supernatural agents evolved by natural selection, but they are highly suggestive and make a good inferential case.     

Hypothesis: The nasal fatigue reflex

Natural selection results in adaptations. I suggest that unexplained fatigue may be an adaptive response to nasal impairment. For macrosmatic animals, intact olfaction is necessary to detect predators. In such animals, any reflex (e.g., fatigue) triggered by nasal dysfunction that limited exposure would offer great survival advantage. The “fatigued” animal would remain in its protected environment, unexposed to hungry carnivores, while the nose healed. In humans, clinical syndromes associated with unexplained fatigue (chronic fatigue syndrome, tension fatigue syndrome, allergic fatigue, neurasthenia, etc.) are characterized by symptoms that, in part, are nasal in origin. The older medical literature does describe the resolution of fatigue in neurasthenia after nasal treatments. Nasal reflexes in animals do cause significant systemic effects, including an inhibition of muscle action potentials that is, perhaps, analogous to the “heavy-limbed” sensation of those with fatigue.     

Children,childhood, and development in evolutionary perspective

We examine children, childhood, and development from an evolutionary perspective. We begin by reviewing major assumptions of evolutionary–developmental psychology, including the integration of “soft” developmental systems theory with ideas from mainstream evolutionary psychology. We then discuss the concept of adaptive developmental plasticity and describe the core evolutionary concept of developmental programming and some of its applications to human development, as instantiated in life history theory and the theory of differential susceptibility to environmental influence. We then discuss the concept of adaptation from an evolutionary–developmental perspective, including ontogenetic and deferred adaptations, and examine the development of some adaptations of infancy and childhood from the domains of folk psychology and folk physics. We conclude that evolutionary theory can serve as a metatheory for developmental science.     

Predator odor avoidance as a rodent model of anxiety: learning-mediated consequences beyond the initial exposure

Prey animals such as rats display innate defensive responses when exposed to the odor of a predator, providing a valuable means of studying the neurobiology of anxiety. While the unconditioned behavioral and neural responses to a single predator odor exposure have been well documented, the paradigm can also be used to study learning-dependent adaptations that occur following repeated exposure to a stressor or associated stimuli. In developing preclinical models for human anxiety disorders this is advantageous, as anxiety disorders seldom involve a single acute experience of anxiety, but rather are chronic and/or recurring illnesses. Part 1 of this review summarizes current research on the three most commonly used predator-related odors: cat odor, ferret odor, and trimethylthiazoline (a component of fox odor). Part 2 reviews the learning-based behavioral and neural adaptations that underlie predator odor-induced context conditioning, one-trial tolerance, sensitization, habituation and dishabituation.

Mental states in animals: cognitive ethology

This article addresses the question of mental states in animals as viewed in 'cognitive ethology'. In effect, this field of research aims at studying naturally occurring behaviours such as food caching, individual recognition, imitation, tool use and communication in wild animals, in order to seek for evidence of mental experiences, self-awareness and intentionality. Cognitive ethologists use some philosophical concepts (e.g., the 'intentional stance') to carry out their programme of the investigation of natural behaviours. A comparison between cognitive ethology and other approaches to the investigation of cognitive processes in animals (e.g., experimental animal psychology) helps to point out the strengths and weaknesses of cognitive ethology. Moreover, laboratory attempts to analyse experimentally intentional behaviours such as deception, the relationship between seeing and knowing, as well as the ability of animals to monitor their own states of knowing, suggest that cognitive ethology could benefit significantly from the conceptual frameworks and methods of animal cognitive psychology. Both disciplines could, in fact, contribute to the understanding of which cognitive abilities are evolutionary adaptations.     

Biological specializations for speech: what can the animals tell us?

Language research over the past 40 years converges on the speech-is-special hypothesis (SiS), according to which speech perception and production are uniquely human adaptations. SiS is grounded in a variety of biological, developmental, and behavioral evidence. In some comparative studies, speechlike stimuli have seemed to cause nonhuman animals to exhibit humanlike performance functions. Auditorists—who believe that spoken language processing is executed by, and is explicable in terms of, general auditory mechanisms—have seized upon such studies as evidence that SiS is incorrect. However, it is difficult to identify biological and functional similarities across different species on the basis of behavior alone, and the elaborate training regimen that nonhuman animals require to achieve human performance levels undermines the significance of certain comparative studies. Both comparative and human behavioral research, including brain-imaging studies of functional localization, electrophysiological recordings of the neural basis of the perception-production link, and developmental studies of a time-locked schedule of language learning, favor SiS over auditorism.

Providing Relationship Interventions to Same-Sex Couples: Clinical Considerations,Program Adaptations,and Continuing Education

Despite remarkable similarities to different-sex couples in terms of core relationship processes and outcomes, same-sex couples differ from different-sex couples in important ways, including relational strengths (e.g., more egalitarian) and challenges associated with their sexual minority identity (e.g., discrimination). Given that most cognitive-behavioral relationship interventions have been designed for and tested on different-sex couples, clinicians wishing to serve same-sex couples will need to make appropriate adaptations to these interventions in order to remove heterosexist bias and sensitively meet the unique needs of same-sex couples. Further, clinicians should strive to be culturally competent in serving this population by developing knowledge of same-sex couple dynamics and issues, and by building a sense of comfort working with these families, which may involve addressing personal biases. The current paper seeks to provide an introduction to same-sex couple relational processes, and offers clinical recommendations and intervention adaptations to better serve this population. Some examples will refer to the development of the Strengthening Same-Sex Relationships programs, culturally sensitive relationship education programs specifically designed for and successfully piloted with male and female same-sex couples.     

Strategies,context, and the mechanism of response inhibition

A series of four experiments investigated Neill’s 11977) claim that there are inhibitory mechanisms in selective attention. It was demonstrated that the evidence supporting the inhibitory theory, namely, the diminished availability of distractor responses during a discretetrials version of the Stroop task is complicated by a number of strategic adaptations to various contingencies within the trial sequence. These results do not support a simple interpretation of response inhibition during the Stroop task.     

Making inferences about the location of hidden food: social dog, causal ape

Domestic dogs (Canis familiaris) and great apes from the genus Pan were tested on a series of object choice tasks. In each task, the location of hidden food was indicated for subjects by some kind of communicative, behavioral, or physical cue. On the basis of differences in the ecologies of these 2 genera, as well as on previous research, the authors hypothesized that dogs should be especially skillful in using human communicative cues such as the pointing gesture, whereas apes should be especially skillful in using physical, causal cues such as food in a cup making noise when it is shaken. The overall pattern of performance by the 2 genera strongly supported this social-dog, causal-ape hypothesis. This result is discussed in terms of apes' adaptations for complex, extractive foraging and dogs' adaptations, during the domestication process, for cooperative communication with humans.     

Reliability,stability, and relationships between infant and parent temperament

Reliability, stability, and relationships between infant and parent temperament were assessed using infant adaptations of 2 childhood temperament inventories. Both scales were moderately reliable, stability was moderate for the 4- to 18-month periods, and significant correlations were noted between mother and infant temperament ratings.     

Dialectical Behavior Therapy for Adolescents: Theory, Treatment Adaptations, and Empirical Outcomes

Dialectical behavior therapy (DBT) was originally developed for chronically suicidal adults with borderline personality disorder (BPD) and emotion dysregulation. Randomized controlled trials (RCTs) indicate DBT is associated with improvements in problem behaviors, including suicide ideation and behavior, non-suicidal self-injury (NSSI), attrition, and hospitalization. Positive outcomes with adults have prompted researchers to adapt DBT for adolescents. Given this interest in DBT for adolescents, it is important to review the theoretical rationale and the evidence base for this treatment and its adaptations. A solid theoretical foundation allows for adequate evaluation of content, structural, and developmental adaptations and provides a framework for understanding which symptoms or behaviors are expected to improve with treatment and why. We first summarize the adult DBT literature, including theory, treatment structure and content, and outcome research. Then, we review theoretical underpinnings, adaptations, and outcomes of DBT for adolescents. DBT has been adapted for adolescents with various psychiatric disorders (i.e., BPD, mood disorders, externalizing disorders, eating disorders, trichotillomania) and problem behaviors (i.e., suicide ideation and behavior, NSSI) across several settings (i.e., outpatient, day program, inpatient, residential, correctional facility). The rationale for using DBT with these adolescents rests in the common underlying dysfunction in emotion regulation among the aforementioned disorders and problem behaviors. Thus, the theoretical underpinnings of DBT suggest that this treatment is likely to be beneficial for adolescents with a broad array of emotion regulation difficulties, particularly underregulation of emotion resulting in behavioral excess. Results from open and quasi-experimental adolescent studies are promising; however, RCTs are sorely needed.     

Jealousy,Infidelity, and the Difficulty of Diagnosing Pathology: A CBT Approach to Coping with Sexual Betrayal and the Green-Eyed Monster

Humans have evolved adaptations for infidelity, as well defenses against a partner’s betrayal—centrally the emotion of jealousy. Both create problems that bring couples to therapy. Diagnosing jealousy as pathological versus normal turns out to be difficult, in part because infidelity has evolved to be concealed from the betrayed mate, which creates a signal detection problem. Because missing an infidelity committed by a mate has been more costly in evolutionary currencies than falsely suspecting a partner of cheating, selection has created an error management cognitive bias to over-infer a partner’s betrayal. Moreover, adaptations for jealousy become activated by predictors of infidelity, such as mate value discrepancies, when no actual infidelities have occurred. Cognitive-behavior therapy (CBT) offers several ways to deal with these complexities. One way is to highlight potential mismatches, distinguishing between jealous emotions that were functional in ancestral environments but are less so in modern environments. A second is to distinguish between the goal of personal well-being and reproductive outcomes. Understanding the evolutionary logic of jealousy, in short, provides patients with conceptual tools for cognitively reframing jealousy and infidelity.     

Fetal programming of stress responses

Epidemiological studies have shown that small size at birth is associated with an increased risk of coronary heart disease and its risk factors, including hypertension and Type 2 diabetes.It is suggested that these observations linking low birthweight with disease result from an imbalance between fetal nutrient demand and supply. This imbalance results in metabolic and endocrine adaptations, which benefit the fetus in the short term by reducing fetal growth and increasing fuel availability, but in the longer term they are maladaptive leading to an increased risk of coronary heart disease. Experimental data in animals and recent human observations have suggested that alterations in the set point of the hypothalamic-pituitary-adrenal axis and sympathoadrenal system are important long-term changes that occur in association with reduced fetal growth. These data suggest that the nature and amplitude of the stress response may be determined by intrauterine factors.
