Sex differences in adolescent ethanol drinking to behavioral intoxication

Rodent models have been especially useful for investigating adolescent ethanol exposure. However, there is a paucity of studies examining sex differences in behavioral intoxication from adolescent ethanol drinking. Here, we used an ethanol drinking model to investigate if adolescent rats of both sexes readily drink ethanol to measurable behavioral intoxication, indicated by increased impulsive action and motor incoordination. Beginning on postnatal day (P) 28, male and female Long‐Evans rats were given 30‐min access to a solution of sucrose (20%) or sweetened ethanol (20% sucrose +15% ethanol) every other day until P60 and once after 2 weeks of forced abstinence (on P75). On alternate (nondrinking) days, rats were reinforced with a food pellet for making a cued nosepoke response. Beginning on P56, rats were tested in this task after drinking sessions to assess ethanol‐induced changes in impulsive action, defined as premature responding prior to cue presentation. Motor coordination was assessed before and after drinking sessions using an incline plane test. Adolescent male and female rats readily consumed ethanol to behavioral intoxication, measured as reduced motor coordination. Following forced abstinence, females displayed greater ethanol‐induced impulsive action. These studies provide evidence for sex differences in behavioral intoxication following adolescent ethanol drinking.     

Caregiving Behavior Is Associated With Decreased Mortality Risk

ABSTRACT— Traditional investigations of caregiving link it to increased caregiver morbidity and mortality, but do not disentangle the effects of providing care from those of being continuously exposed to an ailing loved one with serious health problems. We explored this possible confound in a national, longitudinal survey of elderly married individuals ( N = 3,376). Results showed that spending at least 14 hr per week providing care to a spouse predicted decreased mortality for the caregiver, independently of behavioral and cognitive limitations of the care recipient (spouse), and of other demographic and health variables. These findings suggest that it may be premature to conclude that health risks for caregivers are due to providing active help. Indeed, under some circumstances, caregivers may actually benefit from providing care.     

On the role of depersonalization in Merleau-Ponty

This essay considers the role of depersonalization in the philosophy of Merleau-Ponty. While there has been a modest amount of interest in depersonalization from a phenomenological perspective, a critical exploration of the theme of depersonalization in Merleau-Ponty’s thinking itself remains overlooked (cf. Varga (Philosophy, Psychiatry, and Psychology, 19:2, 103-113, 2012); Colombetti and Ratcliffe (Emotion Review, 4:2, 145-250, 2012). This is an oddity, given that the theme of depersonalization proves instructive in Merleau-Ponty’s account of the constitution of the subject, and appears within Phenomenology of Perception at key points in his thinking (Merleau-Ponty 2012). This paper serves as a critical exposition of the role of depersonalization in Merleau-Ponty’s thought. I proceed in three ways. In the first instance, I provide an overview of depersonalization, addressing its salient characteristics, which includes: a feeling of disturbed bodily subjectivity; a diminishment of affective feeling; and a corresponding and overarching sense of unreality, carrying with it a sense of estrangement. In the main part of the paper, I consider the articulation of depersonalization in Merleau-Ponty, especially as it figures in Phenomenology of Perception. My claim is that depersonalization can be best captured as an expression of Merleau-Ponty’s idea of ambiguity. I conclude by considering to what extent Merleau-Ponty’s account of depersonalization corresponds with the medical understanding of the condition.     

Motives matter: The emotional consequences of recalled self- and other- focused prosocial acts

Past research has demonstrated that engaging in and reflecting upon past instances of prosocial behavior promote happiness. Yet, people provide help for a myriad of reasons. Do the motives for giving impact its emotional consequences? In three experiments (N?>?680), we compared the emotional outcomes of recalling a past instance of prosocial behavior motivated by self-focused and other-focused concerns. Using both between and within subjects designs, we find that recalling an instance of other-focused helping leads to higher positive affect than recalling an instance of self-focused helping. This finding was mediated by feelings of morality. The present work suggests that not all acts of kindness offer equivalent well-being benefits and that selfish motives may undermine the emotional rewards that typically follow other-focused prosocial behavior.     

Coping with spousal loss: potential buffering effects of self-reported helping behavior

The present study examined the role of self-reported helping behavior in attenuating the helper's depression following spousal loss. Using archival data from the Changing Lives of Older Couples sample (N = 289), the study shows that among bereaved participants who had experienced high loss-related grief, helping behavior (providing instrumental support to others) was associated with an accelerated decline in depressive symptoms for the helper from 6 months to 18 months following spousal loss. This relationship between giving help and recovery from depression was independent of support received, as well as measured health, and interpersonal and demographic factors. Implications of these results for theoretical approaches to the study of close relationships and well-being are discussed.     

Do realistic reverberation levels reduce auditory distraction?

Acoustically treated ceilings and wall panels can be used as part of a strategy to reduce the impact of background sound on the health and performance of employees by decreasing the reverberation times of the office noise. In this article we examine the impact of two reverberation times upon task performance. A cognitive task known to be a sensitive index of auditory distraction (serial recall) was used to assess the degree of distraction associated with two types of ceiling: a hard ceiling, such as plasterboard, and a soft ceiling, such as an acoustically treated ceiling. Office noise (in the range 65–75 dB (A)) was found generally to be disruptive relative to a quiet control condition but there was no difference in performance with regard to the ceiling types.

Reduction in auditory distraction by retrieval strategy

Most research on auditory distraction on task performance focuses on those features of the sound that determine a drop in efficiency, with scant regard for examining the processing properties inherent in the focal task. We report how one such property, retrieval strategy, can also influence the degree of disruption by background sound. Using a task that called for the retrieval of realistic train journey information, we showed that retrieval by categories of verbal sequences was not susceptible to disruption by office sound - 65-75 dB(A). However, versions of the task requiring either free or serial recall showed evidence of disruption, a pattern of results consistent with the changing-state account of the irrelevant sound effect, which highlights the key role of serial rehearsal in determining disruption.     

The confounded nature of angry men and happy women

Findings of 7 studies suggested that decisions about the sex of a face and the emotional expressions of anger or happiness are not independent: Participants were faster and more accurate at detecting angry expressions on male faces and at detecting happy expressions on female faces. These findings were robust across different stimulus sets and judgment tasks and indicated bottom-up perceptual processes rather than just top-down conceptually driven ones. Results from additional studies in which neutrally expressive faces were used suggested that the connections between masculine features and angry expressions and between feminine features and happy expressions might be a property of the sexual dimorphism of the face itself and not merely a result of gender stereotypes biasing the perception.     

Disruption of short-term memory by changing and deviant sounds: support for a duplex-mechanism account of auditory distraction

The disruption of short-term memory by to-be-ignored auditory sequences (the changing-state effect) has often been characterized as attentional capture by deviant events (deviation effect). However, the present study demonstrates that changing-state and deviation effects are functionally distinct forms of auditory distraction: The disruption of visual-verbal serial recall by changing-state speech was independent of the effect of a single deviant voice embedded within the speech (Experiment 1); a voice-deviation effect, but not a changing-state effect, was found on a missing-item task (Experiment 2); and a deviant voice repetition within the context of an alternating-voice irrelevant speech sequence disrupted serial recall (Experiment 3). The authors conclude that the changing-state effect is the result of a conflict between 2 seriation processes being applied concurrently to relevant and irrelevant material, whereas the deviation effect reflects a more general attention-capture process.     

A Bivariate Generalized Linear Item Response Theory Modeling Framework to the Analysis of Responses and Response Times

A generalized linear modeling framework to the analysis of responses and response times is outlined. In this framework, referred to as bivariate generalized linear item response theory (B-GLIRT), separate generalized linear measurement models are specified for the responses and the response times that are subsequently linked by cross-relations. The cross-relations can take various forms. Here, we focus on cross-relations with a linear or interaction term for ability tests, and cross-relations with a curvilinear term for personality tests. In addition, we discuss how popular existing models from the psychometric literature are special cases in the B-GLIRT framework depending on restrictions in the cross-relation. This allows us to compare existing models conceptually and empirically. We discuss various extensions of the traditional models motivated by practical problems. We also illustrate the applicability of our approach using various real data examples, including data on personality and cognitive ability.
