Influence of object size on baseline identification, priming, and explicit memory

We investigated the influence of size on identification, priming, and explicit memory for color photos of common objects. Participants studied objects displayed in small, medium, and large sizes and memory was assessed with both implicit identification and explicit recognition tests. Overall, large objects were easier to identify than small objects and study-to-test changes in object size impeded performance on explicit but not implicit memory tests. In contrast to previous findings with line-drawings of objects but consistent with predictions from the distance-as-filtering hypothesis, we found that study-test size manipulations had large effects on old/new recognition memory test for objects displayed in large size at test but not for objects displayed small or medium at test. Our findings add to the growing body of literature showing that the findings obtained using line-drawings of objects do not necessarily generalize to color photos of common objects. We discuss implications of our findings for theories of object perception, memory, and eyewitness identification accuracy for objects.     

癌症患者家属人格特征、应对方式与消极情绪的关系

为探讨癌症患者家属人格特征、应对方式与消极情绪的关系,对128例癌症患者家属进行调查。结果显示,神经质、消极应对方式、癌症危险认知与消极情绪呈显著正相关;积极应对方式、外向与消极情绪呈显著负相关;外向、神经质、癌症危险认知、消极应对方式均影响癌症患者家属的消极情绪,而消极应对方式为神经质人格特征、癌症危险认知和消极情绪的中间变量。

The impact of hope, self-esteem, and attributional style on adolescents’ school grades and emotional well-being: A longitudinal study

We examined the distinctiveness of three “positive thinking” variables (self-esteem, trait hope, and positive attributional style) in predicting future high school grades, teacher-rated adjustment, and students’ reports of their affective states. Seven hundred eighty-four high school students (382 males and 394 females; 8 did not indicate their gender) completed Time 1 measures of verbal and numerical ability, positive thinking, and indices of emotional well-being (positive affect, sadness, fear, and hostility), and Time 2 measures of hope, self-esteem, and emotional well-being. Multi-level random coefficient modelling revealed that each positive thinking variable was distinctive in some contexts but not others. Hope was a predictor of positive affect and the best predictor of grades, negative attributional style was the best predictor of increases in hostility and fear, and low self-esteem was the best predictor of increases in sadness. We also found that sadness at Time 1 predicted decreases in self-esteem at Time 2. The results are discussed with reference to the importance of positive thinking for building resilience.     

How iconic gestures enhance communication: an ERP study

EEG was recorded as adults watched short segments of spontaneous discourse in which the speaker's gestures and utterances contained complementary information. Videos were followed by one of four types of picture probes: cross-modal related probes were congruent with both speech and gestures; speech-only related probes were congruent with information in the speech, but not the gesture; and two sorts of unrelated probes were created by pairing each related probe with a different discourse prime. Event-related potentials (ERPs) elicited by picture probes were measured within the time windows of the N300 (250-350 ms post-stimulus) and N400 (350-550 ms post-stimulus). Cross-modal related probes elicited smaller N300 and N400 than speech-only related ones, indicating that pictures were easier to interpret when they corresponded with gestures. N300 and N400 effects were not due to differences in the visual complexity of each probe type, since the same cross-modal and speech-only picture probes elicited N300 and N400 with similar amplitudes when they appeared as unrelated items. These findings extend previous research on gesture comprehension by revealing how iconic co-speech gestures modulate conceptualization, enabling listeners to better represent visuo-spatial aspects of the speaker's meaning.     

Celebrating a common finding: Riding’s CSA test is unreliable

This paper is a reply to Redmond and colleagues’ brief report that argues we (Peterson et al., 2003a) were not the first to establish the unreliability of the computerised cognitive styles analysis (CSA) test because we used a copy of the test rather than the original. We refute this suggestion and argue that we have already defended our approach to testing the CSA’s reliability (Peterson et al., 2003b) and that our method is entirely appropriate and transparent. Rather than argue over who was the first to test the CSA’s reliability, we believe we should celebrate the fact that we both found the same result, regardless of the method used.     

Top-down predictions in the cognitive brain

The human brain is not a passive organ simply waiting to be activated by external stimuli. Instead, we propose that the brain continuously employs memory of past experiences to interpret sensory information and predict the immediately relevant future. The basic elements of this proposal include analogical mapping, associative representations and the generation of predictions. This review concentrates on visual recognition as the model system for developing and testing ideas about the role and mechanisms of top-down predictions in the brain. We cover relevant behavioral, computational and neural aspects, explore links to emotion and action preparation, and consider clinical implications for schizophrenia and dyslexia. We then discuss the extension of the general principles of this proposal to other cognitive domains.     

中国高中学生中的反应风格及其效应

通过测试正反向陈述的NEO-FFI和EPQ,探讨了中国高中生中默认、极端化、折中化、弹性反应风格的特点,及题目陈述方向的改变对其人格测验信效度的影响。结果发现反应风格在中国高中生中确实存在,折中化和弹性风格对测验的影响最为严重,其次为极端化风格,默认风格则可能不算一种偏差。NEO-FFI量表在使用反向陈述题目时信效度下降,说明由于教育水平低而使高中生理解反向题时存在困难     

Cognitive Moderators of the Longitudinal Association Between Peer Rejection and Adolescent Depressive Symptoms

This longitudinal study examined peer rejection as a predictor of adolescent depressive symptoms during the critical developmental period associated with substantial increases in the prevalence of girls' depression. In a sample of 158 adolescents aged 15-17 years, a peer nomination, sociometric assessment was conducted to examine adolescents' peer status at an initial time point, along with self-report measures of depressive symptoms, depressogenic attributions, and peer importance. Adolescents completed a second measure of depressive symptoms 17 months later. Results were consistent with integrated cognitive vulnerability-stress and cognitive dissonance models, particularly for girls. Specifically, peer rejection was a significant prospective predictor of depressive symptoms when combined with high levels of importance ascribed to peer status and high levels of adolescents' depressogenic attributional styles.
