When asked to hold an infant, 60-85% of adults hold on their left, so that the infant's head is to the left of their midline (Brüser, 1981; de Chateau, 1983; Saling & Tyson, 1981). The same group bias has been found even when persons are merely asked to imagine holding an infant (Nakamichi & Takeda, 1995; Harris, Almerigi, & Kirsch, 2000). A number of variables have been found to contribute modestly to the bias, including the sex and handedness of the holder. In the current study, the role of a new variable is investigated, namely, the feeling of comfort for holding an infant on a particular side as indexed by one's foot preference for acts of stabilizing or postural support. To test this hypothesis, 282 right-handed college students (218 women, 64 men) were given the imagine-hold task along with 4 questions about their foot preference for posture and balance. The results showed that, at least for women, the two measures were modestly but significantly related. 相似文献

Analyses of trial sequences in flanker tasks have revealed cognitive adaptation, reflected in a reduced interference effect
following incompatible trials (Gratton, Coles, & Donchin, 1992). These effects have been explained on the basis of the response
conflict monitoring model of Botvinick, Braver, Barch, Carter, and Cohen (2001), who proposed that preceding response conflict
triggers stronger topdown control, leading to performance improvements on subsequent trials of similar context. A recent study
(Mayr, Awh, & Laurey, 2003) has challenged this account, suggesting that the behavioral adaptations are confined to trial
sequences of exact trial repetitions and can therefore be explained by repetition priming. Here, we present two experiments
in which the sequential dependency effect was present even on trial sequences that did not involve stimulus repeats. We discuss
the data with respect to the conflict-monitoring and repetition-priming accounts. 相似文献

The role of cluster B and C personality disturbance in the course of depression: a prospective study 总被引:1,自引:0,他引:1
Iacoviello BM Alloy LB Abramson LY Whitehouse WG Hogan ME 《Journal of personality disorders》2007,21(4):371-383
The association between personality disturbance and depression has been noted consistently. Prospective tests of personality's impact on the course of depression, however, are lacking. In a sample of 159 undergraduates who experienced at least one prospective depressive episode, dimensional scores for clusters B and C personality disturbance were examined as prospective predictors of four indicators of the course of depression: severity, episode duration, symptomatic chronicity and number of episodes. Cluster C personality disturbance, characterized by anxious and fearful features, predicted depression chronicity. Cluster B, characterized by dramatic, emotional and/or erratic features, predicted severity and duration of depression. The findings are discussed in terms of the possible mechanisms underlying the effects of clusters B and C, as well as implications for future research. 相似文献

The view that remember and know responses can be explained within a dual-process framework has recently been questioned (e.g., Gardiner, Konstantinou, Karayianni, & Gregg, 2005). The aims of the present study were to investigate further discrepancies between remember/know (R/K) studies and dual-process models of recognition memory. In two experiments participants were required to make old/new and R/K decisions under full and divided attention conditions. Experiment 1 used a two-step R/K procedure and showed that attention during retrieval reduced overall recognition performance. Experiment 2 used a one-step R/K procedure and showed that dividing attention at retrieval only affected know responses, suggesting that knowing but not remembering relies on controlled retrieval processes. These findings and findings from recent research provide evidence that is inconsistent with the dual-process explanation for R/K research. 相似文献

The abuse of alcohol and other substances by mothers raising adolescent children has serious adverse effects on family functioning
and youth outcomes, and on mothers’ own health and adaptation. Mothers who are also HIV-infected face additional challenges.
In the present report, we describe a multi-session intervention conducted in individual sessions for mothers with alcohol
and other substance use problems who are raising adolescent children. We outline the primary components of the intervention
and include case studies and examples of exercises and tools. We found that engagement with the intervention and high rates
of attendance were facilitated by tapping into mothers’ desires to improve their relationships with their adolescent children,
the use of a harm reduction approach toward substance use, and intensive outreach. We also discuss lessons learned in the
course of implementing and evaluating the intervention. 相似文献

Neuroimaging has identified an overlapping network of brain regions whose activity is modulated by mood and cognition. Studies of depressed individuals have shown changes in perception, attention, memory, and executive functions. This suggests that mood has a pervasive effect on cognition. Direct evidence of the effect of sad mood on cognition is surprisingly limited, however. Published studies have generally addressed a single cognitive ability per study because the fleeting nature of laboratory-induced mood precludes extended testing, and robust findings are limited to mood effects on memory for emotional stimuli. In this study, sad mood was induced and prolonged, enabling the effects of mood to be assessed for an array of abilities, including those that share neural substrates with sad mood and those affected by depression. Sad mood affected memory for emotional words and facial emotion recognition, but not the other processes measured, with a significant nonuniformity of effect over tasks. These results are consistent with circumscribed effects of sad mood on certain emotion-related cognitive processes, but not on cognition more generally. 相似文献

Self-control relies on glucose as a limited energy source: willpower is more than a metaphor 总被引:2,自引:0,他引:2
Gailliot MT Baumeister RF DeWall CN Maner JK Plant EA Tice DM Brewer LE Schmeichel BJ 《Journal of personality and social psychology》2007,92(2):325-336
The present work suggests that self-control relies on glucose as a limited energy source. Laboratory tests of self-control (i.e., the Stroop task, thought suppression, emotion regulation, attention control) and of social behaviors (i.e., helping behavior, coping with thoughts of death, stifling prejudice during an interracial interaction) showed that (a) acts of self-control reduced blood glucose levels, (b) low levels of blood glucose after an initial self-control task predicted poor performance on a subsequent self-control task, and (c) initial acts of self-control impaired performance on subsequent self-control tasks, but consuming a glucose drink eliminated these impairments. Self-control requires a certain amount of glucose to operate unimpaired. A single act of self-control causes glucose to drop below optimal levels, thereby impairing subsequent attempts at self-control. 相似文献

Physical Environmental Adversity and the Protective Role of Maternal Monitoring in Relation to Early Child Conduct Problems 总被引:1,自引:0,他引:1
Research on the development of externalizing behaviors during early childhood has focused on child and parenting factors. Fewer studies have investigated effects of aversive features of the micro-level physical environment, such as overcrowding and chaos in the home, and the macro-level environment, such as neighborhood quality. This study extends research on physical environmental factors by examining their association with children's early externalizing behaviors, and exploring how maternal monitoring may serve as a protective factor in such contexts. 120 male toddlers at high risk for developing early externalizing behaviors were followed from ages 2 to 5 years. Direct longitudinal associations were found for micro-level environmental factors beginning at age 2 and for neighborhood risk beginning at age 3. Maternal monitoring served as a protective factor for child externalizing behaviors in the context of neighborhood risk. Implications for prevention research and the development of early externalizing behaviors are discussed. 相似文献
