Curt Richter: psychobiology and the concept of instinct

Curt Richter is at the origins of psychobiology in the United States. For Richter the concept of instinct was central to his research. While he had diverse interests that traversed a great range of psychobiology, the concept of instinct was fundamental to his research on specific hungers and the regulation of the internal milieu. Debates about the concept of instinct would last the bulk of Richter's experimental career, culminating in an international conference a decade after the Second World War.     

Failure of sodium- and calcium-deficient rats to acquire conditioned taste aversions to the object of their specific hunger.

Attempts were made to condition taste aversions to the objects of two mineral-specific hungers. Both the innate preference of adrenalectomized rats for sodium and the learned preference of parathyroidectomized rats for calcium were studied. None of the sodium-deficient rats poisoned after drinking sodium chloride (NaCl) reached a taste-avoidance criterion, even after nine pairings of salt ingestion with aversive lithium chloride injections. Six of 11 calcium-deficient rats did not meet the salt-avoidance criterion after 10 pairings. Nondeficient control subjects learned to avoid these salt solutions completely after an average of only three such pairings. Besides unmasking a surprising degree of similarity between the learned and innate specific hungers studied, the results clearly demonstrate a powerful influence of physiological need on aversion conditioning.     

Automatic Emotion Regulation

How do people effectively regulate their emotional reactions? Why are some people better at this than others? Most prior research has addressed these questions by focusing on deliberate forms of emotion regulation. We argue that this focus has left out an important aspect of emotion regulation, namely, automatic emotion regulation (AER). Our review of the behavioral literature suggests that AER is pervasive in everyday life, and has far‐reaching consequences for individuals’ emotions. However, the behavioral literature has yet to address the mechanisms underlying the observed effects. Because it is difficult to directly measure the processes involved in AER, evidence from neuroscientific studies is particularly helpful in addressing these questions. Our review of the neuroscientific literature suggests distinct neural bases for different types of AER, which provides important clues about the cognitive and behavioral processes that might be involved in AER.     

Comparison of Behavioral Belief Structures in the Physical Activity Domain

Behavioral belief structures were evaluated in the physical activity domain along 4 dimensions: positive–negative, affective–instrumental, distal–proximal, and specific motive. Participants completed 19 behavioral belief items and a measure of intention. These behavioral beliefs were subsequently classified on each dimension by 2 independent judges. Results using structural equation modeling showed that positive–negative, affective–instrumental, and proximal–distal dimensions each improved fit over a single behavioral belief construct. Division by affective–instrumental and positive–negative yielded the best fit, compared to single dimensions, but no division resulted in adequate model fit. Indeed, fit continued to improve as each dimension was added, but this specificity came with incumbent multicollinearity when trying to use the constructs for prediction purposes.     

Potassium chloride preference in normal,sodium—and sodium—potassium—deficient rats

KCl water preference was examined in diet-replete, sodium-and sodium—potassium-deficient postpubertal rats of different ages. While diet-replete rats displayed a KCl preference-aversion profile similar to that found using other salts, when retested 30 days later, these same animals had no KCl preference. Na-and Na—K-deficient rats preferred KCl over a broad range of concentrations when tested in early postpuberty and the Na—K-deficient group had a markedly reduced KCl preference threshold (0.12%) when compared to all other groups in the study. But Na-and Na—K-deficient rats older by 2 1/2 months did not prefer KCl. The notion of specific food hungers can be invoked to account for some of the preferences. But hedonics, age and KCl experience must also be considered based on (1) the quantities of KCl consumed, (2) the preference reversals within animals, as well as (3) the significantly increased heart—and kidney—body weight ratios in the rats with the greatest KCl preference.     

Relation of Behavioral and Psychological Involvement to a New Four-Factor Conceptualization of Work-Family Interference

The relation of role involvement to work-family interference has had inconsistent results in past research. By paying closer conceptual attention to the measurement of role involvement and work-family interference, this study addresses past inconsistent findings. First, a new four-factor measure of work-family interference is proposed that incorporates the dimension of externally generated versus internally generated conflict, which has been ignored in previous research. Second, role involvement is considered from both a behavioral and a psychological perspective. Data were obtained from a sample of 534 employed adults with families. The results suggest that a mapping of behavioral and psychological involvement to specific dimensions of external and internal work- family interference appears to be important when examining the general relation of role involvement to work-family interference.     

Flavor Fatigue: Cognitive Depletion Influences Consumer Enjoyment of Complex Flavors

Surprisingly, little research has examined how consumer responses to specific flavor characteristics of food are formed or how they may fluctuate situationally. We address this lacuna in the literature on the hedonic appreciation of food by demonstrating that enjoyment along one important gustatory dimension, flavor complexity, varies with the degree to which consumers are mentally depleted. Specifically, showing that gustatory sensations are more cognitively demanding than previously thought, findings from three studies evince that cognitive depletion reduces consumer enjoyment of complex‐flavored (but not simple‐flavored) foods via a reduction in pleasure that otherwise can be derived from complex flavors. We establish this effect across three different food categories and provide preliminary evidence for consumers’ ability to identify flavors as the underlying process. Our findings offer theoretical contributions and avenues for future research.     

Dissociating averageness and attractiveness: attractive faces are not always average

Although the averageness hypothesis of facial attractiveness proposes that the attractiveness of faces is mostly a consequence of their averageness, 1 study has shown that caricaturing highly attractive faces makes them mathematically less average but more attractive. Here the authors systematically test the averageness hypothesis in 5 experiments using both rating and visual adaptation paradigms. Visual adaptation has previously been shown to increase both preferences for previously viewed face types (i.e., attractiveness) and their perceived normality (i.e., averageness). The authors used a visual adaptation procedure to test whether facial attractiveness is dependent upon faces' proximity to average (averageness hypothesis) or their location relative to average along an attractiveness dimension in face space (contrast hypothesis). While the typical pattern of change due to visual adaptation was found for judgments of normality, judgments of attractiveness resulted in a very different pattern. The results of these 5 experiments conclusively support the proposal that there are specific nonaverage characteristics that are particularly attractive. The authors discuss important implications for the interpretation of studies using a visual adaptation paradigm to investigate attractiveness.     

The issue of force and energy in behavioral change

The issue of force and energy in behavioral change involves the following question. Assuming that certain ideas or cognitions help individuals to change their basic personality structure, is it important that these ideas be conveyed by the therapists, or by the clients, to themselves, in a vigorous, forceful and dramatic manner? This question, along with the concomitant one of “intellectual” versus “emotional” insight, has been neglected and avoided in much of the recent literature. This article considers these questions, tries to formulate an operational definition of force and energy in behavioral change, and suggests some specific things that clients may do to achieve “emotional” insight or elegant philosophic reconstruction.     

Spirituality and Meditative Practice: Research Opportunities and Challenges

Meditative practices have a long history in India and have influenced contemporary meditative programs elsewhere in the world. Over the last several decades, the use of meditation as a therapeutic tool has been investigated in regard to physical, emotional and behavioral effects with impressive results. In parallel to this has been a growing interest in research on spirituality, spiritual growth, and therapeutic modalities that incorporate the spiritual dimension of the person. Ironically, very little research has explored the interface between these two constructs, despite how closely linked they are traditionally. This paper addresses the range of ways in which spirituality and spiritual development might be fruitfully investigated in the context of meditative practice, bringing further understanding to both psychological constructs. Furthermore, the widely recognized significance of both meditative and spiritual experiences suggests that cross-cultural research may be particularly valuable at identifying factors that engage the universal human capacity of spirituality, and the particular potential for meditative practice in doing so.     

Attachment dimensions and sexual motives

Little research has examined the relation between the attachment behavioral system and the sexual behavioral system, although these two systems, along with the caregiving system, are theorized to constitute romantic love ( Fraley & Shaver, 2000 ; Hazan & Shaver, 1987 ). College students (N = 400) completed measures of two dimensions of attachment style, anxiety and avoidance, and motives for having sex. Anxiety was predicted to be associated with having sex to reduce insecurity and foster intense intimacy. Avoidance was predicted to correlate inversely with having sex to foster intimacy and positively with nonromantic goals, such as increasing one's status and prestige among peers. The results supported both sets of predictions. People high on the attachment anxiety dimension reported having sex to reduce insecurity and establish intense closeness; people high on the attachment avoidance dimension reported having sex to impress their peer group, especially if they were having casual, uncommitted sex. Theoretical and practical implications of the findings are discussed.     

任务维度和任务无关维度干扰信息的同质性影响视觉搜索的神经机制

在三个实验中, 我们利用功能性磁共振成像(functional magnetic resonance imaging, fMRI)技术考察了在简单特征搜索任务和客体内联合搜索任务中任务维度干扰项的同质性(或称一致性, homogeneity)和任务无关维度干扰信息的同质性对视觉搜索行为的影响及其神经机制。主要探讨了三个问题：(1) 任务维度干扰信息的同质性与目标存在性之间交互作用的神经机制; (2) 任务维度干扰信息的同质性与任务无关维度干扰信息的同质性之间的交互作用及其神经机制; (3) 上述神经机制在不同类型的视觉搜索(特征搜索和联合搜索)中的异同。     

Generalization and discrimination of shape orientation in the pigeon

Pigeons learned to peck a green key on which parallelogram-shapes were projected; they then received generalization tests in which the orientation of the parallelogram was varied. Nondifferential training produced very little eventual stimulus control along the orientation dimension, but when training included S- trials (absence of the parallelogram) subjects responded consistently more to certain orientations than to others. Unlike typical results for visual generalization (e.g., line-tilt), the tilt gradients obtained for this complex stimulus were bimodal, supporting predictions on the basis of human perceptual data. However, unimodal gradients could be produced by specific discrimination training along the orientation dimension. Other forms of intradimensional training also produced relatively steep gradients, often characterized by unexpected but consistent secondary peaks. An attempt to obtain inhibitory gradients (S+: green key; S-: parallelogram on a green background) resulted in virtually zero responding all along the shape-orientation dimension; therefore, specific inhibitory control could not be evaluated. All these experiments suggest that definition of this complex stimulus dimension in terms of mere "angular orientation" is inappropriate, and alternative interpretations are discussed.     

Profiles in Problem Solving: Psychological Well-Being and Distress Among Persons with Diabetes Mellitus

Although social problem-solving abilities have been consistently associated with indicators of behavioral health, this work has been largely confined to tests of specific theoretical issues. Research has yet to demonstrate how the separate elements of the social problem-solving model relate to different patterns of adjustment, particularly among persons who live with chronic disease. We studied the occurrence of different profiles of social problem-solving abilities observed among persons living with diabetes mellitus. We then examined differences between clusters on measures of life satisfaction and depression. Results indicate that distinct profiles in problem-solving abilities do occur and these groupings can be distinguished by their different patterns of adjustment. Implications for theoretical models of problem solving and clinical assessment and interventions for persons with diabetes are discussed.     

Folded additive structures: A nonpolynomial model of some factorial interactions

A nonpolynomial measurement model for representing nonadditive compositions of stimulus dimensions is presented. This representation, which is referred to as a folded additive structure, permits the decomposition of a behavioral ordering into independent factors in some of the cases where the behavior itself does not directly reflect this independence. Psychologically, this representation corresponds to a model of behavior which assumes that (1) the effect stimulus attributes have on behavior is mediated by a single relevent psychological dimension, (2) the behavioral ordering is single-peaked over this mediating dimension and (3) the mediating dimension has a conjoint additive ordering over a set of relevent stimulus dimensions. Necessary and sufficient tests for folded additive structures are given. In addition, five psychological theories which make these assumptions are discussed.     

Dialectical Behavior Therapy Applied to Parent Skills Training: Adjunctive Treatment for Parents With Difficulties in Affect Regulation

Poor outcomes in parent training programs have been associated with parental psychopathology in general, and difficulties in parental affect regulation in particular. Although many parents may be able to learn behavioral management skills in a controlled therapy setting, for those who experience affect dysregulation, generalization of these skills to the natural environment may be challenging when their emotions are aroused. Parents, particularly those who struggle with affect dysregulation around their child's behavior, may benefit from dialectical behavior therapy (DBT) because it specifically targets problems in emotion regulation. Thus, the purpose of this article is to discuss relevant aspects of DBT (e.g., dialectics, biosocial model, and validation) and highlight its applicability to parents who struggle with affect dysregulation. Several clinical case studies will also be presented to elucidate how mental health professionals can address the affect dysregulation in parents by teaching them DBT skills to manage their own negative emotions, particularly when their child's behavior is the source of emotional arousal.     

Persistence and relapse of reinforced behavioral variability

The present study examined persistence and relapse of reinforced behavioral variability in pigeons. Pigeons emitted four‐response sequences across two keys. Sequences produced food according to a lag schedule, in which a response sequence was followed by food if it differed from a certain number of previous sequences. In Experiment 1, food was delivered for sequences that satisfied a lag schedule in both components of a multiple schedule. When reinforcement was removed for one component (i.e., extinction), levels of behavioral variability decreased for only that component. In Experiment 2, food was delivered for sequences satisfying a lag schedule in one component of a multiple schedule. In the other component, food was delivered at the same rate, but without the lag variability requirement (i.e., yoked). Following extinction, levels of behavioral variability returned to baseline for both components after response‐independent food delivery (i.e., reinstatement). In Experiment 3, one group of pigeons responded on a lag variability schedule, and the other group responded on a lag repetition schedule. For both groups, levels of behavioral variability increased when alternative reinforcement was suspended (i.e., resurgence). In each experiment, we observed some evidence for extinction‐induced response variability and for variability as an operant dimension of behavior.     

Food reinforcement and eating: a multilevel analysis

Eating represents a choice among many alternative behaviors. The purpose of this review is to provide an overview of how food reinforcement and behavioral choice theory are related to eating and to show how this theoretical approach may help organize research on eating from molecular genetics through treatment and prevention of obesity. Special emphasis is placed on how food reinforcement and behavioral choice theory are relevant to understanding excess energy intake and obesity and how they provide a framework for examining factors that may influence eating and are outside of those that may regulate energy homeostasis. Methods to measure food reinforcement are reviewed, along with factors that influence the reinforcing value of eating. Contributions of neuroscience and genetics to the study of food reinforcement are illustrated by using the example of dopamine. Implications of food reinforcement for obesity and positive energy balance are explored, with suggestions for novel approaches to obesity treatment based on the synthesis of behavioral and pharmacological approaches to food reinforcement.     

The functional theory of counterfactual thinking.

Counterfactuals are thoughts about alternatives to past events, that is, thoughts of what might have been. This article provides an updated account of the functional theory of counterfactual thinking, suggesting that such thoughts are best explained in terms of their role in behavior regulation and performance improvement. The article reviews a wide range of cognitive experiments indicating that counterfactual thoughts may influence behavior by either of two routes: a content-specific pathway (which involves specific informational effects on behavioral intentions, which then influence behavior) and a content-neutral pathway (which involves indirect effects via affect, mind-sets, or motivation). The functional theory is particularly useful in organizing recent findings regarding counterfactual thinking and mental health. The article concludes by considering the connections to other theoretical conceptions, especially recent advances in goal cognition.
