How self‐compassion moderates the effect of body surveillance on subjective happiness and depression among women

According to objectification theory (Fredrickson & Roberts, 1997), being treated as an object leads women to engage in self‐objectification, which in turn increases body surveillance and body shame as well as impairs mental health. However, very little is known about what factors could act as buffers against the detrimental consequences of self‐objectification. This paper seeks to understand the role of self‐compassion (the ability to kindly accept oneself or show self‐directed kindness while suffering) in the perception that women have of their own bodies. Results indicate that self‐compassion moderated the effect of body surveillance on depression and happiness separately among women. More specifically, for women low in self‐compassion, body surveillance was negatively associated with happiness, which was explained by increased depression. In sum, our results indicate that self‐compassion protects against the detrimental consequences of body surveillance.     

Age-of-acquisition and subjective frequency estimates for all generally known monosyllabic French words and their relation with other psycholinguistic variables

Ratings for age of acquisition (AoA) and subjective frequency were collected for the 1,493 monosyllabic French words that were most known to French students. AoA ratings were collected by asking participants to estimate in years the age at which they learned each word. Subjective frequency ratings were collected on a 7-point scale, ranging from never encountered to encountered several times daily. The results were analyzed to address the relationship between AoA and subjective frequency ratings with other psycholinguistic variables (objective frequency, imageability, number of letters, and number of orthographic neighbors). The results showed high reliability ratings with other databases.

Motives for secondary social sharing of emotions

This study provides new evidence of motives of secondary social sharing of emotions. In a retrospective study, 140 female (Mage = 29.4 yr., SD=12.8) and 116 male (M = 29.5 yr., SD = 13.1) participants were asked to recall a recent situation in which they had talked to a third person about a positive or negative, low or high intensity emotional narrative they had heard. 70% of the respondents reported having secondarily shared the reported event rapidly after the narration with several persons and at several times. Moreover, they not only described the event, the speaker's reaction and their own reactions, but also revealed the identity of their first confidant. Participants reported having spread the emotional narrative more widely in the high negative condition in order to seek emotional support and social comparison.     

Additive utility without restricted solvability on every component

It is shown that restricted solvability need not be required to hold w.r.t. every component for deriving the existence of additive utilities: additive representations can be shown to exist even when restricted solvability holds w.r.t. only two components. In such cases, the uniqueness property of these representations departs from the classical theory in that it is between ordinal and cardinal.     

Sex Differences in Effectiveness of Extended-Release Stimulant Medication among Adolescents with Attention-Deficit/Hyperactivity Disorder

This study examined whether adolescent females with attention-deficit/hyperactivity disorder (ADHD) are differentially responsive than their male counterparts to extended-release stimulant medications. This investigation may bear special importance for an adolescent (as opposed to child) population, because hormonal and metabolism differences between sexes are most likely to emerge at this time. Male (n = 19) and female (n = 16) adolescents, ages 16–19 with ADHD, participated in a randomized, double-blind crossover study evaluating the effectiveness of osmotic-release methylphenidate, extended release amphetamine salts, placebo, and routine limited medication regimen. Medication efficacy was evaluated using ADHD symptom ratings from adolescent self-report and parent report, along with objective measures of inattention and hyperactivity/impulsivity during driving performance and neuropsychological tasks. Males and females were largely equivalent in impairment, and medication was similarly effective in reducing symptoms. No interactions were found between sex and medication on any measure of effectiveness or side effects. This finding suggests that the efficacy and tolerability of extended-release stimulant medications is equivalent for male and female adolescents with ADHD.     

The hippocampus and prefrontal cortex are differentially involved in serial memory retrieval in non-stress and stress conditions

We previously showed that 24 h after learning, mice significantly remembered the first (D1) but not the second (D2) discrimination in a serial spatial task and that an acute stress delivered 5 min before the test phase reversed this memory retrieval pattern.A first experiment evaluated the effects of dorsal hippocampus (HPC) or prefrontal cortex (PFC) lesions, these two brain areas being well-known for their involvement in serial and spatial memory processes. For this purpose, six independent groups of mice were used: non-lesioned (controls), PFC or HPC-lesioned animals, submitted or not to an acute stress (electric footshocks; 0.9 mA). Results show that (i) non-stressed controls as well as PFC-lesioned mice (stressed or not) remembered D1 but not D2; (ii) stressed controls and HPC-lesioned mice (stressed or not) remembered D2 but not D1; (iii) stress significantly increased plasma corticosterone in controls and PFC-lesioned mice, but not in HPC-lesioned mice which already showed a significant plasma corticosterone increase in non-stressed condition.Since data from this first experiment showed that stress inhibited the hippocampal-dependent D1 memory retrieval, a second experiment evaluated the behavioral effect of intrahippocampal corticosterone injection in non-stressed mice. Results show that intrahippocampal corticosterone injection induced a reversal of serial memory retrieval pattern similar to that induced by acute stress.Overall, our study shows that (i) in non-stress condition, the emergence of D1 is HPC-dependent; (ii) in stress condition, the emergence of D2 requires the PFC integrity; moreover, intrahippocampal corticosterone injection mimicked the effects of stress in the CSD task.     

ON THE EFFICIENCY OF VISUAL SELECTIVE ATTENTION:

Abstract— The ability to ignore irrelevant peripheral distractors was assessed as a junction of the efficiency in visual search for a target at the center of display. Efficient target search, among dissimilar nontargets, led to greater distraction than inefficient search, among similar nontargets. This seemingly paradoxical result is predicted by the recent proposal (Lavie, 1995a) that irrelevant processing can be prevented only by increasing the load for relevant processing. Varying the set size of similar items in the central search task demonstrated that interference from irrelevant distractors was eliminated only with more than four relevant items. These results demonstrate how capacity limits determine the efficiency of selective attention, and raise questions about some standard assumptions of most visual search models.     

Teaching Prosocial Behavior to Typically Developing Toddlers

Toddlers in day care have more toy conflicts, aggression, and peer-inflicted injuries than any other age group. Toddlers are also capable of turn-taking and affectionate behavior, but exhibit these prosocial behaviors less often than aggression and toy-taking. We explored the usefulness and feasibility of contextual and teacher-directed social skills intervention for increasing toddlers' turn-taking and affectionate behavior to peers. Results showed that adding tangible consequences to a basic package of contextual arrangement, prompts, and praise was the most effective strategy for increasing both turn-taking and affection. Aggression decreased when affection or turn-taking increased.     

STM Experimenter: Using HyperCard and MacRecorder in short-term memory experiments

We describe a Macintosh program for the presentation of spoken word lists in short-term memory (STM) experiments. The program was developed with the use of HyperCard and MacRecorder. Parameters such as rate of item presentation, number of items per trial, and number of trials per block may be adjusted by the experimenter. The program features high-quality digitized sound, trial-to-trial word list randomization, and data logging. Computer-based experimentation offers several advantages over traditional approaches that involve tape recordings or lists read aloud by the experimenter. Methodological improvements afforded by computer-controlled item administration are discussed.     

Self-reports of depression and state-trait anxiety: evidence for differential assessment.

Several researchers have found anxiety and depression to be indistinguishable in nonclinical samples and have suggested that both constructs may be components of a general psychological distress process. Another possibility is that overlap is due to the psychometric limitations of scales used. A series of exploratory factor analyses were conducted in a nonclinical sample (N = 605) using the Beck Depression Inventory (BDI; Beck, 1978), the State-Trait Anxiety Inventory (STAI; Spielberger, 1983), and the Endler Multidimensional Anxiety Scales (EMAS; Endler, Edwards, & Vitelli, 1991). Both state and trait anxiety and depression could be differentiated with the BDI and the EMAS but not with the STAI. Some theoretical models of negative affectivity or general psychopathology may be premature.
