Routine cognitive errors: a trait-like predictor of individual differences in anxiety and distress

Five studies (N=361) sought to model a class of errors--namely, those in routine tasks--that several literatures have suggested may predispose individuals to higher levels of emotional distress. Individual differences in error frequency were assessed in choice reaction-time tasks of a routine cognitive type. In Study 1, it was found that tendencies toward error in such tasks exhibit trait-like stability over time. In Study 3, it was found that tendencies toward error exhibit trait-like consistency across different tasks. Higher error frequency, in turn, predicted higher levels of negative affect, general distress symptoms, displayed levels of negative emotion during an interview, and momentary experiences of negative emotion in daily life (Studies 2-5). In all cases, such predictive relations remained significant with individual differences in neuroticism controlled. The results thus converge on the idea that error frequency in simple cognitive tasks is a significant and consequential predictor of emotional distress in everyday life. The results are novel, but discussed within the context of the wider literatures that informed them.     

Agency affects adults', but not children's, guessing preferences in a game of chance

Adults and children have recently been shown to prefer guessing the outcome of a die roll after the die has been rolled (but remained out of sight) rather than before it has been rolled. This result is contrary to the predictions of the competence hypothesis (Heath & Tversky, 1991 ), which proposes that people are sensitive to the degree of their relative ignorance and therefore prefer to guess about an outcome it is impossible to know, rather than one that they could know, but do not. We investigated the potential role of agency in guessing preferences about a novel game of chance. When the experimenter controlled the outcome, we replicated the finding that adults and 5- to 6-year-old children preferred to make their guess after the outcome had been determined. For adults only, this preference reversed when they exerted control over the outcome about which they were guessing. The adult data appear best explained by a modified version of the competence hypothesis that highlights the notion of control or responsibility. It is proposed that potential attributions of blame are related to the guesser's role in determining the outcome. The child data were consistent with an imagination-based account of guessing preferences.     

自谦的研究综述

对自谦的思考由来已久,但是,直到二十一世纪初,人们才试图借助科学手段对自谦进行系统的研究。在心理学界,自谦仍是一个新的研究领域。自谦涉及谦礼、谦敬、谦卑、谦忍,与谦虚、谦逊密切相关。文章通过文献资料的搜集,从自谦的界定、自谦的测量、自谦的相关因素、自谦的研究取向等四个方面进行了综述。     

Sweet taste preferences and experiences predict prosocial inferences, personalities, and behaviors

It is striking that prosocial people are considered "sweet" (e.g., "she's a sweetie") because they are unlikely to differentially taste this way. These metaphors aid communication, but theories of conceptual metaphor and embodiment led us to hypothesize that they can be used to derive novel insights about personality processes. Five studies converged on this idea. Study 1 revealed that people believed strangers who liked sweet foods (e.g., candy) were also higher in agreeableness. Studies 2 and 3 showed that individual differences in the preference for sweet foods predicted prosocial personalities, prosocial intentions, and prosocial behaviors. Studies 4 and 5 used experimental designs and showed that momentarily savoring a sweet food (vs. a nonsweet food or no food) increased participants' self-reports of agreeableness and helping behavior. The results reveal that an embodied metaphor approach provides a complementary but unique perspective to traditional trait views of personality.     

Sameness of Fregean sense

This paper develops a criterion for sameness of Fregean senses. I consider three criteria: logical equivalence, intensional isomorphism, and epistemic equipollence. I reject the first two and argue for a version of the third.     

Indirect object recognition: evidence for associative processes in recognition memory

Rats' exploration of stimulus P (e.g., a domestic object) is reduced following either its direct exposure or its indirect exposure and is taken to indicate recognition memory. Procedures for demonstrating indirect object recognition involve an initial presentation of object P with stimulus X (and of an object Q with stimulus Y). On test, stimulus X is presented with objects P and Q and rats' exploration of Q exceeds their exploration of P. One interpretation here is that the presentation of stimulus X on test associatively activates the memory of object P, which diminishes exploration of P relative to Q. It is possible, instead, that performance is simply the result of a novel pattern of stimulation generated by the unfamiliar combination of X and Q. The authors modified this procedure to reduce the likelihood of such a process. Their procedure involved first the presentation of PX and QY before the presentation of stimulus X alone. During the test that followed, objects P and Q were presented but stimulus X was removed. The authors found that exploration of Q remained greater than that of P despite these modifications and discuss some theoretical implications of indirect, associative processes in recognition memory.     

When aggressive individuals see the world more accurately: the case of perceptual sensitivity to subtle facial expressions of anger

Previous research has suggested that aggressive individuals exhibit a bias to perceive nonangry expressions as angry. Another line of thinking, however, posits that aggression is a learned response to hostile environments and should be linked to social-cognitive skills suited to such environments. If so, aggressive individuals may exhibit greater perceptual sensitivity to subtle facial cues of anger. Three studies were conducted to test this proposal. In them, participants' ability to discriminate between subtly different intensities of facial anger was tested. Aggressive participants generally displayed greater perceptual sensitivity to subtle cues of facial anger. This pattern could not be explained in terms of response bias and was specific to angry expressions. The results thus support the idea that aggression is associated with social-cognitive skills rather than bias and ineptitude.     

Psychoedukation bei Personen mit erh?htem Psychoserisiko

Background

So far only few studies are available which have evaluated the effectiveness of psychoeducation for individuals at risk of psychosis in the early initial prodromal state (EIPS) whereas the benefit of psychoeducation in psychotic patients has been repeatedly confirmed. Thus the aim of this study was to investigate the effect of psychoeducation in individuals with increased risk of psychosis in the EIPS.

Method

A total of 128 help-seeking outpatients in the EIPS participated in a randomized controlled multicentre trial of 12 months of either psychoeducation as part of an integrated psychological intervention (IPI) or supportive counseling (SC). The time to transition to psychosis at 12-month and 24-month follow-up as well as the social adjustment at baseline, time of transition or post-treatment by means of the social adjustment scale (SAS?II) were assessed.

Results

The IPI was superior to SC in preventing progression to psychosis at 12-month (3.2% versus 16.9%, p?=0.008) and 24-month follow-up (6.3% versus 20.0%, p?=0.019). Both treatments resulted in significant pre-post improvements in SAS?II with no significant differences between the two groups.

Conclusions

Psychoeducation as part of an integrated intervention is effective for preventing the onset of psychosis over a 24-month time period in people in an EIPS. Moreover patients at risk of developing first episode psychosis seem to benefit from a specific psychoeducational intervention in the context of other treatments as well as from SC.     

纤维乳管镜临床应用中的问题与争议

纤维乳管镜主要应用于乳头溢液的诊断,提高了诊断的准确率,减小了手术切除范围,并修改了部分乳腺疾病的手术指征.但由于乳腺导管系统解剖的复杂性以及乳管镜本身的限制,乳管镜在乳腺导管内病变的切除、导管炎症治疗、乳腺癌筛查、保乳手术中辅助判定切缘等临床应用方面,尚存在诸多的问题与争议.
