威胁性刺激注意偏向的时间进程

注意偏向各成分间关系及发生时间进程尚存争议。本研究以情绪图片为刺激,采用类别判断任务,通过眼动技术探讨正常个体对威胁性刺激注意偏向的时间进程。结果显示,(1)向左的首次眼跳概率高于向右,而潜伏期短于向右,存在左侧偏向;(2)注意回避发生在250ms以内,解除锁定困难发生在400ms之后;(3)注意偏向影响类别判断过程。结果表明,注意回避与左侧偏向在威胁性刺激注意偏向形成早期存在相互作用,且比解除锁定困难更早发生。     

When an Object Appears Unexpectedly: Object Circumvention in Adults

Obstacles often appear unexpectedly in our pathway and these require us to make immediate adjustments. Despite how regularly we encounter such situations only few studies have considered how we adjust to unexpected obstacles in the pathway that require us to walk around them. The authors considered how adults adjust to the possibility of an obstacle appearing and then also how foot placement is adjusted to circumvent an obstacle. Fifteen healthy adults walked down an 11-m walkway, initially they were told this was a clear pathway and nothing in the environment would change (no gate), they then performed a series of trials in which a gate may (gate close) or may not (gate open) partially obstruct their pathway. The authors found that mediolateral trunk velocity and acceleration was significantly increased when there was the possibility of an obstacle but before the obstacle appeared. This demonstrates an adaptive walking strategy that seems to enable healthy young adults to successfully circumvent obstacles. The authors also categorized foot placement adjustments and found that adults favored making shorter and wider steps away from the obstacle. They suggest this combination of adjustments allows participants to maintain stability while successfully circumventing the obstacle.     

Mentoring as a Mediator or Moderator of the Association between Racial Discrimination and Coping Efficacy in Urban,Low‐Income Latina/o Youth

The aim of this study was to examine the associations among mentoring relationship quality (i.e., relational and instrumental quality), racial discrimination and coping efficacy with racial discrimination. Three social support models were tested, including the stress buffering, support mobilization, and support deterioration models. Participants were 257 urban, low‐income Latina/o high school students, who completed surveys in both 9th and 10th grades. While controlling for gender and coping efficacy with discrimination in 9th grade, results supported the social support deterioration model. Specifically, there was a significant indirect effect of racial discrimination in 9th grade on coping efficacy in 10th grade through instrumental mentoring quality. As racial discrimination increased, mentoring quality decreased and then coping efficacy decreased. We also found that more racial discrimination in 9th grade was significantly associated with lower coping efficacy in 10th grade, and higher instrumental mentoring quality in 9th grade was significantly associated with higher coping efficacy in 10th grade, while controlling for gender and coping efficacy in 9th grade. Implications and recommendations for future research are discussed.     

Matching between oral inward–outward movements of object names and oral movements associated with denoted objects

In eight experiments, we explored matching effects between oral approach–avoidance movements triggered by word articulation and meaning of the objects the words denoted. Participants (total N?=?1264) rated their liking for words that featured consonantal muscle stricture spots either wandering inwards (e.g., BODIKA, resembling ingestion movements) or outwards (e.g., KODIBA, resembling expectoration movements). These words were labelled as names for various objects. For objects the use of which entails ingestive oral actions (lemonade and mouthwash) inward words were preferred over outward words. For objects that trigger expectorative oral actions (toxical chemical, pill, and bubble gum) this preference was attenuated or even reversed (outward words were liked more than inward). Valence of the denoted object did not play a role in these modulations. Thus, the sagittal direction of mouth movements during silent reading meaningfully interacted with direction of oral actions associated with the denoted objects.     

The timeline of threat processing in repressors: more evidence for early vigilance and late avoidance

Evidence is mixed concerning whether individuals with a repressive coping style can actually selectively avoid threatening stimuli. Recent research (Calvo & Eysenck, 2000) on repressors’ threat processing suggests that it is necessary to take into account the timeline of this bias. A spontaneous trait inference paradigm was used here to test the hypothesis that repressors would, relative to others, be less likely to infer unfavorable and threatening traits. However, if pressured to make trait inferences quickly, it was predicted that they would be less likely than others to infer favorable and unthreatening traits. Repressors and nonrepressors were presented with passages that could have supported positive or negative trait inferences. In Study 1, they were asked to respond to trait words as quickly as possible but were not held accountable for doing so. In Study 2, time pressure was increased to capture uncorrected trait inferences. Results indicated that repressors were more likely to make positive trait inferences than others when simply asked to respond quickly. Under time pressure, this bias disappeared. Results point to the importance of taking into account an important moderator between coping style and threat, namely, the stage of processing at which differences in threat processing are being assessed.     

Young men's coping with androgenetic alopecia: acceptance counts when hair gets thinner

The present study examined how young men cope with balding (androgenetic alopecia). The sample consisted of 160 university students (18–30 years) with varying degrees of hair loss (stages II–VII on the Norwood–Hamilton Scale). Three ways of coping were distinguished: compensation, avoidance, and acceptance. Psychological distress due to hair loss depended neither on the age of participants nor on the stage of balding. Since compensation and avoidance were associated with high levels of distress, their functional value might be questioned. Acceptance, however, was negatively related to distress – even, or rather, especially when stage of hair loss was advanced. Furthermore, acceptance had a direct negative effect on medical consultation about hair loss. By contrast, compensation and avoidance had a positive distress-mediated effect on medical consultation. Taken together, this study underlines the adaptive role of acceptance when confronted with irreversible changes such as androgenetic alopecia.

Enhanced learning by posttrial injection of H1-but not H2-histaminergic antagonists into the nucleus basalis magnocellularis region

The aim of this study was to examine the effects of histaminergic antagonists on memory upon injection into the region of the nucleus basalis magnocellularis (NBM). In experiment 1, rats with chronically implanted cannulae were trained on the uphill avoidance task, which involves a punishment of a high-probability turning response on a tilted platform (negative geotaxis). Immediately after the training trial, that is, after a tail shock was administered upon performing the response, rats received one microinjection (0.5 microliter) of H1-receptor blocker chlorpheniramine (dose range 0.1 to 20 microgram) or the H2-receptor blocker ranitidine (same dose range) or saline into the NBM region. When tested 24 h later, rats treated with chlorpheniramine (20 micrograms) had significantly longer uphill latencies than vehicle controls and ranitidine-treated animals, indicative of superior learning of the avoidance response. In experiment 2, a test for possible proactive effects of posttrial chlorpheniramine on performance during the retention trial was performed. Animals were injected with either 20 micrograms chlorpheniramine or saline immediately after the training trial of the uphill task. One chlorpheniramine control group was treated with a delay of 5 h. Additional groups which received chlorpheniramine or vehicle after the training trial but no trail shock were included. When tested 24 h later, rats injected with 20 micrograms chlorpheniramine again exhibited significantly longer uphill latencies than did vehicle-injected rats. Retention latencies for the rats of the chlorpheniramine 5-h delayed group did not differ from those of the vehicle-injected rats, ruling out proactive effects of chlorpheniramine on performance. In summary, the histaminergic H1-blocker chlorpheniramine can enhance mnemonic functioning in addition to its reinforcing effects upon NBM injection as reported previously.
