Can shame memories become a key to identity? The centrality of shame memories predicts psychopathology

This study investigates the premise that a shame memory can become a central component of personal identity, a turning point in the life story and a reference point for everyday inferences. We assessed shame, centrality of shame memory, depression, anxiety, stress and traumatic stress reactions in 811 participants from general population (481 undergraduate students and 330 subjects from normal population) to explore the interactions between these variables. Results show that early shame experiences do indeed reveal centrality of memory characteristics. Furthermore, the centrality of shame memories is associated with current feelings of internal and external shame in adulthood. Key to our findings is that the centrality of shame memories shows a unique and independent contribution to depression, anxiety and stress prediction, even when controlling for shame measures. In addition, our results show that the centrality of shame memories is highly and positively associated with traumatic stress reactions. Copyright © 2010 John Wiley & Sons, Ltd.     

Early predictors of self‐regulation in middle childhood

The present study examined the contribution of caregiving practices at ages 4–5 (Time 1) to children's capacity for self‐regulation at ages 8–9 (Time 2). The multi‐ethnic sample comprised 549 children of National Longitudinal Survey of Youth (NLSY) participants. High levels of maternal warmth and low levels of physically punitive discipline at Time 1 were associated with a greater capacity for self‐regulation at Time 2. These associations remained significant once initial levels of self‐regulation were taken into account, indicating that the development of self‐regulation is open to caregiver influence during childhood. Neither child gender nor ethnicity moderated the effects of early parenting practices on later self‐regulation; the interaction between low maternal warmth and high discipline was also non‐significant. Findings add to the literature on how early parenting practices shape children's capacity for effective self‐regulation, and have implications for researchers and practitioners.

Opposing effects on muscarinic acetylcholine receptors in the piriform cortex of odor-trained rats

We combined pharmacological studies and electrophysiological recordings to investigate modifications in muscarinic acetylcholine (ACh) receptors (mAChR) in the rat olfactory (piriform) cortex, following odor-discrimination rule learning. Rats were trained to discriminate between positive and negative cues in pairs of odors, until they reached a phase of high capability to learn unfamiliar odors, using the same paradigm (“rule learning”). It has been reported that at 1–3 d after the acquisition of odor-discrimination rule learning, pyramidal neurons in the rat piriform cortex show enhanced excitability, due to a reduction in the spike-activated potassium current I_AHP, which is modulated by ACh. Further, ACh and its analog, carbachol (CCh), lost the ability to reduce the I_AHP in neurons from trained rats. Here we show that the reduced sensitivity to CCh in the piriform cortex results from a decrease in the number of mAChRs, as well as a reduction in the affinity of the receptors to CCh. Also, it has been reported that 3–8 d after the acquisition of odor-discrimination rule learning, synaptic transmission in the piriform cortex is enhanced, and paired-pulse facilitation (PPF) in response to twin stimulations is reduced. Here, intracellular recordings from pyramidal neurons show that CCh increases PPF in the piriform cortex from odor-trained rats more than in control rats, suggesting enhanced effect of ACh in inhibiting presynaptic glutamate release after odor training.     

Acculturative stress, social support, and coping: relations to psychological adjustment among Mexican American college students

This study examined the relations between acculturative stress and psychological functioning, as well as the protective role of social support and coping style, in a sample of 148 Mexican American college students (67% female, 33% male; mean age = 23.05 years, SD = 3.33). In bivariate analyses, acculturative stress was associated with higher levels of anxiety and depressive symptoms. Moreover, active coping was associated with better adjustment (lower depression), whereas avoidant coping predicted poorer adjustment (higher levels of depression and anxiety). Tests of interaction effects indicated that parental support and active coping buffered the effects of high acculturative stress on anxiety symptoms and depressive symptoms. In addition, peer support moderated the relation between acculturative stress and anxiety symptoms. Implications for reducing the effects of acculturative stress among Mexican American college students are discussed.     

James’s theory of emotion and affective turn in psychology / La teoría de las emociones de James y el giro afectivo en psicología

Using William James’s classical theory of the emotions, this article discusses the way the relationship between cognition and emotion are predominantly explained and operationalized in contemporary psychology and neuroscience research. Specific aspects of James’s theory are reconstructed, connecting his more general philosophical framework with arguments about the relationship between subjective experience and the process of corporal change. A review published in the journal Cognition & Emotion (C&E) (2001–11) concludes that almost all its literature is based on the idea of interaction between two different processes, while James suggests that the process of experience is one and the same. Dialogue between these two scenarios facilitates the identification of current research potentialities in terms of mixed-method studies and with emphasis on the temporality of action, overall physiological change, and uniqueness of experience.     

This is a Tricky Situation: Situationism and Reasons-Responsiveness

Situations are powerful: the evidence from experimental social psychology suggests that agents are hugely influenced by the situations they find themselves in, often without their knowing it (this, roughly-speaking, is the thesis of situationism). In our paper, we evaluate how situational factors affect our reasons-responsiveness, as conceived of by John Fischer and Mark Ravizza, and, through this, how they also affect moral responsibility. We argue that the situationist experiments suggest that situational factors impair, among other things, our moderate reasons-responsiveness, which is plausibly required for moral responsibility. However, even though we argue that situational factors lower the degree of our reasons-responsiveness, we propose that agents remain moderately reasons-responsive to the degree required for moral responsibility. Nonetheless, those (adversely) affected by situational factors are arguably less morally responsible than those who are not subject to similar situational factors. We further evaluate an understanding of reasons-responsiveness (developed by Manuel Vargas in the light of situationist data) which relativizes reasons-responsiveness to agents’ circumstances. We argue that the situationist data do not warrant this kind of divergence from Fischer’s and Ravizza’s account. We conclude by discussing what situationist experiments tell us about our relationship to non-reasons.     

Sexual risk taking in adolescence: the role of self-regulation and attraction to risk

Precursors of adolescent sexual risk taking were examined in a multiethnic sample consisting of 443 children (51% girls) of National Longitudinal Survey of Youth participants. Respondents were 12-13 years old in 1994 and 16-17 in 1998. Controlling for demographic and contextual factors, self-regulation--but not risk proneness--was significantly (modestly) associated with overall sexual risk taking 4 years later. Analyses of individual sexual behaviors indicated that self-regulation may affect choices made after becoming sexually active (e.g., number of partners) rather than the initiation of sexual activity. Measures of parent and peer influence had independent effects on sexual risk taking but did not moderate the effects of self-regulation and risk proneness. Findings add to the growing literature on implications of self-regulation for individual development.     

Detailed analysis of the male copulatory motor pattern in mammals: hormonal bases

Data obtained, using a polygraphic technique, on the characteristics of the motor and genital copulatory responses of male rabbits, rats, mice, hamsters, and guinea pigs are reviewed. This methodology provided detailed information, not accessible to other analyses, on the frequency and dynamic organization of copulatory pelvic thrusting trains of the species studied. This comparative analysis showed that: (1) The male rat may display two types of ejaculatory responses, differing in the dynamic organization of the pelvic thrusting train, and in the duration of the intravaginal thrusting period preceding ejaculation. (2) In the guinea pigs and small rodents, but not in rabbits, pelvic thrusting at ejaculatory responses persists during intromission, and a period of fast intravaginal thrusting is associated with ejaculation. (3) The motor copulatory pattern of the rabbit, but not of the rat, hamster, or guinea pig, is affected by castration and hormone treatment, suggesting that, in rabbits, androgen acts both on motivation and on the spinal neural systems related to copulation.
