Specifying the boundary conditions of the multimedia effect: The influence of content and its distribution between text and pictures

It was investigated whether the beneficial effect of picture presentation might be influenced by the content conveyed through text and pictures and the way information is distributed between them. Ninety‐nine students learnt in five between‐subjects learning conditions (i.e., text with spatial contents plus pictures, text with visual contents plus pictures, only text with spatial contents, only text with visual contents, only picture) about a tourist centre and a holiday farm. Results showed that pictures (i.e., maps) were beneficial for learning if spatial knowledge had to be acquired, but did not support learning when non‐spatial, visual knowledge had to be acquired. Furthermore, a high overlap of spatial information in text and picture was helpful, which can be explained by the assumption that learning is a text‐guided process. On the other hand, regarding non‐spatial visual information, a high text‐picture overlap did not influence learning, probably because text alone was sufficient for acquiring visual knowledge. The implications of these findings are discussed.     

The role of crossmodal competition and dimensional overlap in crossmodal attention switching

Crossmodal selective attention was investigated in a cued task switching paradigm using bimodal visual and auditory stimulation. A cue indicated the imperative modality. Three levels of spatial S–R associations were established following perceptual (location), structural (numerical), and conceptual (verbal) set-level compatibility. In Experiment 1, participants switched attention between the auditory and visual modality either with a spatial-location or spatial-numerical stimulus set. In the spatial-location set, participants performed a localization judgment on left vs. right presented stimuli, whereas the spatial-numerical set required a magnitude judgment about a visually or auditorily presented number word. Single-modality blocks with unimodal stimuli were included as a control condition. In Experiment 2, the spatial-numerical stimulus set was replaced by a spatial-verbal stimulus set using direction words (e.g., “left”). RT data showed modality switch costs, which were asymmetric across modalities in the spatial-numerical and spatial-verbal stimulus set (i.e., larger for auditory than for visual stimuli), and congruency effects, which were asymmetric primarily in the spatial-location stimulus set (i.e., larger for auditory than for visual stimuli). This pattern of effects suggests task-dependent visual dominance.     

A comparison of self-other agreement in personal values versus the Big Five personality traits

Can we judge other people’s values accurately, or are values too subjective to assess? We compared self-other agreement in personal values with agreement in the Big Five personality traits. Self-other agreement in four higher-order values (median r = .47) and in six culture-specific value factors (median r = .50) was substantial and similar to that for the Big Five personality traits (median r = .51). When corrected for attenuation due to measurement error self-other agreement was high for all three scales (median rs > .65). The results suggest that people can assess values of others whom they know well with remarkable accuracy. Therefore, other-ratings of personal values can be used to validate and complement self-report value measures.     

Your mistakes are mine: Self-other overlap predicts neural response to observed errors

This study examined whether the degree to which one perceives overlap between the self and another person predicts the magnitude of the neural response of the anterior cingulate cortex (ACC) following the observation of that person’s errors. Specifically, we measured the magnitude of the observational feedback-related negativity (oFRN), an event-related potential associated with observing someone else make an error, while participants watched strangers or friends complete a Stroop task. Results show stronger activation of the ACC, as indexed by the oFRN, for those who observed friends compared to those who observed strangers. This effect was mediated by the degree to which participants included the other in their conception of the self. This study contributes a unique examination of real-life close pairs to a growing body of research showing that social factors can greatly impact neural processing.     

Narrating the other: Self-other agreement of affective qualities and manifest events among personal life stories and the vicarious life stories provided by informants

Life stories are psychosocial constructions of one’s past, present, and future. Vicarious stories are mental representations of others’ life stories. Across two studies, we examined self-other agreement among features of participants’ personal and vicarious stories and whether agreement corresponded with relationship closeness. Agreement was quantified via the affective qualities and manifest events of key scenes. Targets’ personal and informants’ vicarious stories demonstrated agreement in tone, but not in redemption or contamination (Study 1). The manifest events within informants’ vicarious scenes corresponded with participants’ personal life stories 25% of the time, and this agreement increased with greater relationship closeness (Study 2). Our findings support the notion that an understanding of the important events in someone’s life may facilitate interpersonal closeness.     

结合a分层的兼具项目曝光和广义测验重叠率控制的选题策略

测验安全和题库使用率在计算机化自适应测验中十分重要, 特别是高风险测验。传统的SHGT法兼具同时控制项目曝光率和广义测验重叠率的功能, 但题库使用率较差。a分层法能够提高题库使用率, 但对过度曝光的项目控制不足。本研究将a分层法的思想与SHGT法相结合, 各取所长, 提出了3种新的选题方法：SHGT_a法, SHGT_b法和SHGT_c法。研究结果表明：(1)与SHGT法相比, 新方法均可以在有效地控制项目曝光率和广义测验重叠率同时, 极大地提高题库使用率; (2)随着预设项目曝光率(rmax)和广义测验重叠率( )取值的增大以及共享人数a的减小, 新方法对被试能力估计的精度呈上升趋势。比起SHGT法, 新方法仍能保持很高的题库使用率; (3)当区分度和难度的相关(rab)较大时, SHGT_b和SHGT_c法在能力估计精度方面优于SHGT_a法; (4)在不同的测验考察内容比例下, 3种新方法对被试能力估计的精度均较好; (5)与SHGT法相比, 新方法能够有效地控制项目曝光率过度控制的问题。

A multi-informant study of the influence of targets’ and perceivers’ social desirability on self-other agreement in ratings of the HEXACO personality dimensions

In the current research we evaluated the impact of socially desirable responding on the strength of self-other agreement in personality judgments. We used a multi-informant design with self- and other-reports of HEXACO personality dimensions as well as self-reported and other-reported social desirability. Analyses were based on 305 primary participants and 709 informants. As shown by the results, neither self-other agreement nor other-other agreement regarding the personality dimensions was affected by social desirability. Furthermore, significant correlations between self-rated and other-rated social desirability emerged. The results are discussed as further evidence that most social desirability scales seem to measure substantive personality traits instead of response styles.
