Latent Classes of Dysregulated Behaviors Relate to Negative Mental Images

Dysregulated behaviors (DBs), such as self-harm or binge eating, are related to various negative outcomes. In this study, we investigate how classes of individuals vary in their level of DBs. We compare the classes with regards to their experiences regarding negative mental images and emotion regulation strategies. A web-based survey assessed eleven DBs in a sample of N=912 adults. A latent class analysis (LCA) identified a class of 168 adults that were prone to various DBs (“high(DBs)”). Another class (n?=?46) reported drunkenness and risks for drug use and overeating (“high(Intake)”). The majority of individuals (n?=?698) featured a low rate of DBs (“low(DBs)”). The high(DBs) exhibited the highest scores in distressing imagery and maladaptive emotion regulation. The high(Intake) had a low overall profile; however, it displayed increased imagery nowness. Class differences were leveled by depressive symptoms. The findings help extend the knowledge on DBs and their correlates. Clinical implications are discussed.     

Depressed mothers' and their infants' interactions with nondepressed partners

Twenty depressed adolescent mothers were videotaped interacting with their own infant and with the infant of a nondepressed mother. In addition, nondepressed mothers were videotaped with their own infant as well as with the infant of a depressed mother. Depressed mothers showed less facial expressivity than nondepressed mothers and received less optimal interaction rating scale scores (a summary score for state, physical activity, head orientation, gaze, silence during gaze aversion, facial expressions, vocalizations, infantized behavior, contingent responsivity, and gameplaying). This occurred independent of whether they were interacting with their own infant versus an infant of a nondepressed mother, suggesting that depressed mothers display less optimal behaviors to infants in general. The infants of both depressed and nondepressed mothers received better head orientation and summary ratings when they were interacting with another mother, perhaps because the other mother was more novel. Infants of nondepressed mothers, in particular, had better summary ratings (state, physical activity, head orientation, gaze, facial expressions, fussiness, and vocalizations) than the infants of depressed mothers when interacting with depressed mothers. Thus, it may be that infants of nondepressed mothers are generally better interaction partners than infants of depressed mothers. Another related possibility is that they persist longer in trying to elicit a response from mothers less responsive than their own, given that they have learned to expect a response to their behavior.     

Inverted U-Shaped Function Between Flow and Cortisol Release During Chess Play

This study focused on the salivary cortisol level and its relation to the two components of flow (flow absorption and flow fluency) in tournament chess players exposed to one of the skill-demand-level manipulations (underload, fit, and overload). The aims of this study were to investigate how skill-demand-level manipulations affect cortisol release and how flow and cortisol release are related in the context of an engaging task. Specifically, the task involved fifty-seven tournament chess players playing chess against a software in one of the experimental groups. We assessed flow after chess playing for 25 min via questionnaire and collected saliva before chess playing (T1), right after chess playing (T2), and 10 min after T2 (T3). Our findings show that cortisol levels were affected by the skill-demand-level manipulations. At T3, participants in the overload group showed higher cortisol levels than participants in the fit and underload groups. There were no differences in cortisol release between the experimental groups at T2. In addition, we found the expected inverted U-shaped relation between cortisol release and flow absorption at T2. A moderate level of cortisol was associated with a higher level of flow absorption. In contrast, a higher level of cortisol was associated with a lower level of flow absorption. Against our expectations, flow fluency was not related to cortisol release. We discuss practical and theoretical implications of our results as well as potential for future research.     

Contingency inattention: against causal debunking in ethics

Philosophical Studies - It is a philosophical truism that we must think of others as moral agents, not merely as causal or statistical objects. But why? I argue that this follows from the best...     

The effects of tail shock on target-biting behavior of confined mice

Mice that are confined in a narrow cylinder readily bite inanimate targets. The following studies were conducted to determine the effects of tail shock on the target biting behavior of two strains of mice. During 20-min daily sessions, ten tail shocks were administered on a fixed-time 2-min schedule. One group of mice received a tone-conditioned stimulus (CS) which terminated with the onset of the shock, and a second group of mice did not. Target bites were collected in eight 15-sec bins over the 2-min trial and cumulated over the session. It was observed that tail shock was followed by an increase in target biting and that there was a comparatively high intershock interval biting rate. In addition, intershock interval biting was suppressed for the duration of the CS. These observations are discussed in terms of the utility of this paradigm for the psychopharmacological assessment of aggressive behavior.     

Detecting changes in simulated events using partial‐interval recording and momentary time sampling

In a series of three studies, we evaluated simulated data with reversal designs to determine whether partial‐interval recording (PIR) and momentary time sampling (MTS) detected changes that were evident with continuous measures. The results from Study 1 showed that MTS with interval sizes up to 30 s detected most of the moderate and large changes in duration events and MTS with interval sizes up to 1 min detected most large changes in duration events. By comparison, PIR with 10‐s intervals detected approximately half of all changes in duration events. The results of Study 2 showed that only 10‐s PIR reliably detected most small, moderate, and large changes in frequency events. The results of Study 3 showed that PIR with 10‐s intervals generated a relatively high percentage of false positives for duration events, whereas MTS did not. As a whole, the results support previous findings, but also provide new guidelines for the use of PIR and MTS. Copyright © 2008 John Wiley & Sons, Ltd.     

Differences in personality between sustained hypertension,isolated clinic hypertension and normotension

The aim of this study was to determine whether there are differences in personality between hypertension and normotension. Forty‐two male patients with essential hypertension were divided into two groups after self‐assessment of blood pressure, 18 with sustained hypertension and 24 with isolated clinic (white coat) hypertension, and were compared with 25 men with normotension on Spielberger's State‐Trait Anxiety Inventory and the Jenkins Activity Survey. In line with hypotheses, the sustained hypertensive group showed higher levels of trait anxiety, Type A behaviour pattern, and hard‐driving behaviours/competitiveness than the normotensive group, whereas isolated clinic hypertensives occupied an intermediate position between those two groups. Results provide support to the hypothesised relationship between personality and hypertension and stress the need of distinguishing sustained hypertension from isolated clinic hypertension.

Sex and culture differences in perceptions of estimated multiple intelligence for self and family: A Macanese1Portuguese comparison

Differences in sex and culture between Macanese and Portuguese university students in self and parental estimations of IQ were examined using Gardner's ( 1999 ) list of 10 multiple intelligences. A total of 197 Macanese (90 male and 107 female) and 331 Portuguese (139 male and 192 female) students participated in the investigation. The following hypotheses were tested: it was anticipated that there would be sex differences in self‐rated mathematical and spatial intelligence, with men giving higher self‐estimates than women; it was predicted that there would be cultural differences between Macanese and Portuguese, with the former awarding themselves and their parents significantly lower scores than the latter; participants would rate their fathers as more intelligent overall than their mothers; the best predictors of overall (g) IQ would be logical/mathematical, spatial, and verbal intelligence. In contrast to previous results (Furnham, 2001 ), when examined separately, gender differences in both self‐estimates and parents estimates did not occur in the Macanese sample. There were, however, consistent and clear culture differences. Portuguese gave higher self and family ratings than Macanese, as expected. Portuguese rated their verbal, body kinetic, interpersonal, intrapersonal, and naturalistic intelligence higher than did Macanese. Portuguese rated verbal, mathematical, spatial, interpersonal, intrapersonal, existential, and naturalistic father's intelligence higher than did Macanese. Portuguese rated verbal, mathematical, spatial, musical, interpersonal, intrapersonal, existential, spiritual, and naturalistic mother's intelligence higher than did Macanese. Participants of both cultures rated overall intelligence of their father higher than that of their mother. This was also to be expected as previous studies have shown this to be the case in terms of gender stereotyping. In both cultures verbal and interpersonal intelligences predict overall intelligence. However, in Macao, body‐kinetic and intrapersonal intelligences, and in Portugal logical and naturalistic intelligences, also predict overall intelligence. Implications of these results for education and self‐presentations are considered.     

Brooding and reflection: rumination predicts suicidal ideation at 1-year follow-up in a community sample

The cognitive processes underlying suicidal thinking and behavior are not well understood. The present study examined brooding and reflection, two dimensions of rumination, as predictors of suicidal ideation among a community sample of 1134 adults. Participants completed self-report measures of rumination and depression, and a semi-structured clinical interview that included an assessment of suicidal ideation, at baseline and 1-year follow-up. Brooding was more strongly related to degree of ideation at baseline than was reflection. However, both brooding and reflection predicted whether an individual thought about suicide at 1-year follow-up, even after adjusting for baseline suicidal ideation. Symptoms of depression mediated the relationship between brooding and ideation but not that between reflection and ideation. Implications for the nature of thought processes that result in suicidal thinking are discussed.
