Reversal learning as a function of changed reward location or changed drive

In two experiments, rats were trained with food in one location (e.g., black alley) and water in another location (white alley) under hunger or thirst. Subsequently, either the locations of the rewards were reversed, or the drive was changed (from hunger to thirst or thirst to hunger). Reversal of instrumental responses took considerably longer when drive was changed and rewards remained in the same locations than when reward locations were reversed. These results were interpreted as indicating that the animal's internal representations of the rewards received in each location transfer when drive is changed. These internal-reward representations interfere with reversal learning by eliciting the responses which were conditioned to them in Phase 1. Because the values of food and water reverse when drive is changed from hunger to thirst or vice versa, it was suggested that the reward representations surviving the drive shift are cognitive representations of the specific events received (food or water), independent of the value of the rewards under either hunger or thirst.     

Asymmetrical interactions between thirst and hunger in pavlovian-instrumental transfer

Pavlovian-instrumental transfer experiments have demonstrated that a stimulus paired with a sucrose solution under hunger will increase instrumental performance under thirst relative to a stimulus previously paired with food pellets. In Experiment 1 it was demonstrated that this difference is, in part, produced by suppression induced by the pellet stimulus, which, it was found, acted to reduce instrumental performance under thirst. In Experiment 2, the reverse shift was examined, comparing the effects of stimuli paired with either a saline solution or a sucrose solution under thirst on instrumental performance under hunger. Although the sucrose stimulus was found to elevate performance when hungry, the saline stimulus was found to be without effect. This asymmetry in the interaction between hunger and thirst is discussed in terms of the way motivational states control the interaction between sensory and affective components of the reinforcer.     

IS SELF-OBJECTIFICATION RELATED TO INTEROCEPTIVE AWARENESS? AN EXAMINATION OF POTENTIAL MEDIATING PATHWAYS TO DISORDERED EATING ATTITUDES

Although there has been considerable empirical support for Objectification Theory ( Fredrickson & Roberts, 1997 ), findings have been mixed regarding self-objectification's relationship to interoceptive awareness, an awareness of one's internal physical and emotional states. We examined whether interoceptive awareness mediated the relationship between self-objectification and disordered eating attitudes, exploring more specifically the relative contributions of difficulties recognizing feelings of hunger and satiety versus emotions. College women ( N = 195) completed measures assessing self-objectification, interoceptive awareness, awareness of emotions, and disordered eating attitudes. Self-objectification correlated significantly more strongly with interoceptive awareness when internal cues about hunger and satiety were assessed. The relationship between self-objectification and disordered eating attitudes was partially mediated by interoceptive awareness. Results revealed that interoceptive awareness may best be captured by a measure that includes lack of awareness of both hunger and satiety and emotional states. Research and clinical implications of these findings are discussed.     

Interoceptive accuracy and panic

Psychophysiological models of panic hypothesize that panickers focus attention on and become anxious about the physical sensations associated with panic. Attention on internal somatic cues has been labeled interoception. The present study examined the role of physiological arousal and subjective anxiety on interoceptive accuracy. Infrequent panickers and nonanxious participants participated in an initial baseline to examine overall interoceptive accuracy. Next, participants ingested caffeine, about which they received either safety or no safety information. Using a mental heartbeat tracking paradigm, participants' count of their heartbeats during specific time intervals were coded based on polygraph measures. Infrequent panickers were more accurate in the perception of their heartbeats than nonanxious participants. Changes in physiological arousal were not associated with increased accuracy on the heartbeat perception task. However, higher levels of self-reported anxiety were associated with superior performance.

My future self: Young children's ability to anticipate and explain future states

Two experiments examine preschool-aged children's ability to anticipate physiological states of the self. One hundred and eight 3-, 4-, and 5-year-olds were presented with stories and pictorial scenes designed to evoke thought about future states such as thirst, cold, and hunger. They were asked to imagine themselves in these scenarios and to choose one item from a set of three that they would need. Only one of the items could be used to address the future state. In both experiments, developmental differences were obtained for correct item choices and types of verbal explanations. In Experiment 2, the performance of the 3- and 4-year-olds was negatively affected by introducing items that were semantically associated with the scenarios but did not address the future state, whereas the 5-year-olds’ performance was not. Results are discussed with respect to children's understanding of the future, theory of mind, and inhibitory control skills.     

Peripheral control of drinking: gastrointestinal filling as a negative feedback signal, a theoretical and experimental analysis.

The studies described here investigated the hypothesis that the osmotic postingestional satiety signal proposed by McCleary operates through a mechanism related to gut filling rather than by osmotically induced shifts of fluid from osmoreceptors in the brain. A control theory model is presented, which was designed to make quantitatively explicit the hypothesis under question. The results showed that when mannitol, which is not absorbed from the intestine, is added to a highly palatable saccharin-glucose mixture, the amount of fluid consumed decreased in inverse proportion to the mannitol concentration. Mannitol was also shown to block fluid absorption from the intestine at a low concentration (approximately .070 M) and at higher concentrations to lead to a net flux of fluid into the intestinal lumen. It was also shown that mannitol in concentrations that reduced the intake of the palatable solution did not induce thirst when the animals were in water balance. It did induce thirst, however, when the animals were tested in a state of negative water balance. The results of these studies, considered as a whole, support the view that McCleary's osmotic postingestional satiety signal acts as an intestinal distention signal rather than by inducing thirst. The model is found to be reasonably accurate as a first approximation, and suggestions are made for improvements.     

Integrating Person- and Function-Centered Approaches in Career Development Theory and Research

In the 1980s, life-span developmental psychology and developmental contextualism were first applied to career development in an effort to update the developmental frameworks most commonly used in vocational psychology. Because the occupational world today is far more dynamic and rapidly changing than even 20 years ago, it stands to reason that changes in the world of occupations need to be matched by theoretical and conceptual advances. One significant advance would be to integrate a person-centered, life course approach exemplified by the work of Bühler, with a function-based, life-span developmental approach that examines certain behaviors or functions (such as career-related behaviors) (Baltes & Goulet, 1970). Prominent researchers in the life course tradition (e.g., Elder) and in the life-span tradition (e.g., Baltes) have, however, pursued separate directions in both theory and research. The present paper will propose that career development theory and research could be a natural area in which the predominantly function-centered approach of life-span psychology can be integrated with the person-centered methodologies and theoretical perspectives exemplified by the life course approach in sociology.

Developmental theory and the practice of clinical child psychology

Examined developmental theory and its relevance for the practice of clinical child psychology. Following a brief review of basic principles of developmental psychology and developmental psychopathology, implications of a developmental perspective are explored for the diagnosis, assessment, and treatment of childhood disorders. Although it is obvious that many developmental issues confront the clinical child psychologist and that we have learned much about translating developmental theory into clinical practice, we conclude we have a long way to go before we can assert that a true developmental-clinical child interface has been realized.

Transfer from discrimination under hunger to discrimination under thirst: The role of expectancy and habit

The experimental group (Group HA-TA) received food (F) and water (W) rewarded trials in an alternating sequence under hunger in Phase 1 and under thirst in Phase 2. Group HA-TA ran faster on F than on W trials in Phase 1, and faster on W than on F trials in Phase 2. Early in Phase 2 the difference between speeds on W and F trials was larger for Group HA-TA than for a group which received no runway training in Phase 1 (Group HO-TA), but later in Phase 2 this difference was larger for Group HO-TA than for Group HA-TA. Also in Phase 2 the difference between speeds on W and F trials was larger for Group HA-TA than for a group which received a random sequence of F and W trials under hunger in Phase 1, and smaller for Group HA-TA than for a group which received alternating F and W trials under thirst in both phases. To interpret these results it was assumed that for Group HA-TA the expectancies of reward formed in Phase 1 facilitated development of alternation performance in Phase 2, but that the S-R associative connections formed in Phase 1 inhibited ultimate development of alternation performance in Phase 2.     

Some new perspectives on conditioned hunger.

One theory holds that appetitive drives such as hunger and thirst are not conditionable because of their slow onset. However, recent evidence has shown only transitory conditioning of appetitive drives even with rapid onset. Such experiments may have failed because: (a) Exteroceptive conditioned stimuli (CSs) used in past experiments may be less easily accociated with the internal hunger drive than are interoceptive taste cues. Experiments 1-3 provided some support for this hypothesis. (b) The dependent measures used in past experiments may not be valid. Experiments 4 and 5 suggested that changes in the rate of bar pressing on an operant extinction curve following probe CSs for hunger may be a more sensitive and valid index of conditioned appetitive drive. However, the elusive and transitory nature of these results demands a reexamination of the basic difference between appetitive and aversive drives, which lies in the mode of their onset and control and which, given adaptive considerations, can account for their widely different conditionability.     

More of myself: Manipulating interoceptive awareness by heightened attention to bodily and narrative aspects of the self

Psychology distinguishes between a bodily and a narrative self. Within neuroscience, models of the bodily self are based on exteroceptive sensorimotor processes or on the integration of interoceptive sensations. Recent research has revealed interactions between interoceptive and exteroceptive processing of self-related information, for example that mirror self-observation can improve interoceptive awareness. Using heartbeat perception, we measured the effect on interoceptive awareness of two experimental manipulations, designed to heighten attention to bodily and narrative aspects of the self. Participants gazed at a photograph of their own face or at self-relevant words. In both experimental conditions interoceptive awareness was significantly increased, compared to baseline. Results show that attention to narrative aspects of self, previously regarded as relying on higher-order processes, has an effect similar to self-face stimuli in improving interoceptive awareness. Our findings extend the previously observed interaction between the bodily self and interoception to more abstract amodal representations of the self.     

Narrative competence and constructive developmental theory: A proposal for rewriting theBildungsroman in the postmodern world

Some of the chief characteristics of the narrative psychology of Bruner, Polkinghorne, Sarbin, Freeman, Howard, and White and Epston are outlined with implications for therapy discussed. Narrative psychology is then related to some current models of adult development, including those of Kegan, Perry, Belenky, Labouvie-Vief, Levinson, Basseches, and Pascual-Leone. Types of narrative competence are discussed and an argument is made that developmental readiness for narrative must be considered if narrative approaches are going to be applied. Different types of narrative approaches are shown to be indicative of particular developmental stages. The social relativism of narrative psychology is addressed and it is argued that developmental models provide a scheme for assessing the maturity of alternative narrative constructions.

Out of Control: Visceral Influences on Behavior

Understanding discrepancies between behavior and perceived self-interest has been one of the major, but largely untackled, theoretical challenges confronting decision theory from its infancy to the present. People often act against their self-interest in full knowledge that they are doing so; they experience a feeling of being “out of control.” This paper attributes this phenomenon to the operation of “visceral factors,” which include drive states such as hunger, thirst and sexual desire, moods and emotions, physical pain, and craving for a drug one is addicted to. The defining characteristics of visceral factors are, first, a direct hedonic impact (which is usually negative), and second, an effect on the relative desirability of different goods and actions. The largely aversive experience of hunger, for example, affects the desirability of eating, but also of other activities such as sex. Likewise, fear and pain are both aversive, and both increase the desirability of withdrawal behaviors. The visceral factor perspective has two central premises: First, immediately experienced visceral factors have a disproportionate effect on behavior and tend to “crowd out” virtually all goals other than that of mitigating the visceral factor. Second, people underweigh, or even ignore, visceral factors that they will experience in the future, have experienced in the past, or that are experienced by other people. The paper details these two assumptions, then shows how they can help to explain a wide range of phenomena: impulsivity and self-control, drug addiction, various anomalies concerning sexual behavior, the effect of vividness on decision making, and certain phenomena relating to motivation and action.     

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.
