The role of the oath in credibility assessment

Based on the adaptive lie detector theory, this study is an examination of whether taking an oath, as context‐general information, increases the credibility of a suspect. The consistency of the testimonies of 6 eyewitnesses was manipulated so that it could be used as individuating information. There were 2 sets of testimonies: one that was consistent and one that was inconsistent. The results supported the adaptive lie detector theory. The participants judged those persons who took an oath to be more credible than those who did not, but this only happened in situations where the testimonies of the eyewitnesses were inconsistent. The theoretical and practical implications of the findings and future directions are then discussed.

Reading is believing: the truth effect and source credibility

Five experiments explored how source reliability influences people’s tendency to rate statements as more credible when they were encountered earlier (the truth effect). Undergraduates read statements from one reliable source and one unreliable source. Statements read multiple times were perceived as more valid and were more often correctly identified on a general knowledge test than statements read once or not at all. This occurred at varying retention intervals whether the statements originated from a reliable or unreliable source, when people had little memory for the statements themselves or their source, and when the discrediting information about the sources came either before or after reading the facts. While repetition aided recognition and source accuracy, both were unaffected by the reliability of the source. Consistent with the source monitoring framework, familiarity may create an illusion of truth for statements when people lack source-specifying cues, especially cues regarding the reliability of the source.     

Using mnemonic images and explicit sound contrasting to help Japanese children learn English alphabet sounds

Although mnemonics have been shown to be effective in remembering letter-sound associations, the use of foreign words as cues for English phonemes had not been investigated. Learning phonemes in Japan is challenging because the Japanese language is based on a different sound unit called mora (mostly consonant-vowel combinations). This study investigated the effectiveness of using mnemonic images utilizing Japanese words as cues for the phonemes, and explicit sound contrasting of phonemic sounds with morae they could be confused with, in facilitating children's acquisition of knowledge about alphabet letter-sound correspondence. The participants were 140 6th-grade Japanese students who were taught phoneme-consonant correspondence, with or without the use of mnemonics or explicit sound contrasting. Analysis of the students’ pre- and post-instruction assessments revealed significant interaction effects between types of instruction provided and instruction phase, indicating better performance in letter-sound association as a consequence of the inclusion of both mnemonics and explicit sound contrasting.     

Anxiety-related differences in affective categorizations of lexical stimuli

Effects of emotional valence on attention have been shown to occur even when stimuli are presented outside awareness. The impact of negative valence on stimulus processing has been demonstrated to be particularly salient in anxiety. Therefore, it has been hypothesized that compared to nonanxious individuals, anxious individuals have an enhanced ability to detect the valence of negative stimuli. However, it remains unclear whether anxious individuals are better at identifying the valence of threatening stimuli or, rather, more likely to label ambiguous stimuli as threatening. To investigate these hypotheses, high and low anxious participants categorized lexical stimuli as "safe" or "dangerous." Stimuli were presented at durations that allowed for both conscious (unmasked) and nonconscious (masked) processing. Results show that on masked trials, anxious individuals evidenced an enhanced ability to correctly classify threatening information, whereas nonanxious participants demonstrated an enhanced ability to correctly classify neutral or positive information. Signal detection analyses indicated results were explained by a response bias, whereby anxious individuals were more likely than nonanxious individuals to categorize masked words as threatening and nonanxious individuals were more likely to categorize masked words as nonthreatening. No group differences for nonword stimuli emerged, suggesting that anxiety-related response bias tendencies are activated only after detection of a weak semantic signal.

Gender stereotypes and motor performance: How explicit and implicit stereotypes influence girls standing long jump and anxiety

ObjectivesInducing a negative stereotype toward women usually leads to a decrease in women's motor performance. Given that most studies have focused on explicit stereotype induction among adults, the main aim of this study was to investigate the effects of explicit and implicit gender stereotypes on standing long jump performance in children. The second aim was to investigate the effects of these same manipulations on children’s state anxiety.DesignA mixed model design with within-between-subject was used with standing long jump performance and state anxiety as dependent variables.MethodTwo hundred and four children (Mage = 10.95 years, SDage = 0.85) participated in this study and were randomly assigned, after baseline measurement, into four different groups (i.e., explicit/implicit vs. explicit vs. implicit vs. control). Specifically, participants performed 8 trials of standing long jump (4 trials during the baseline phase and 4 trials during the experimental phase). Children also completed the competitive state Anxiety Inventory at baseline as well as immediately after the trials.ResultsFor motor performance, children in the explicit/implicit group and in the implicit group were negatively affected by the stereotype manipulation during all trials whereas participants in the explicit group were only negatively impacted during the last two trials. However, regarding state anxiety, children were negatively affected after both explicit only and implicit only manipulations and more significantly after explicit/implicit manipulation.ConclusionsThe present research showed that the explicit and implicit manipulations influenced motor performance differently, but that these two manipulations increased state anxiety in the same way. Moreover, the combination of the explicit and implicit inductions leads to a greater significant negative influence on state anxiety but not motor performance.     

Sense of agency: Sensorimotor signals and social context are differentially weighed at implicit and explicit levels

Sense of agency (SoA) describes the experience of being the author of an action. Cue integration approaches divide SoA into an implicit level, mostly relying on prospective sensorimotor signals, and an explicit level, resulting from an integration of sensorimotor and contextual cues based on their reliability. Integration mechanisms at each level and the contribution of implicit to explicit SoA remain underspecified. In a task of movements with visual outcomes, we tested the effect of social context (contextual cue) and sensory prediction congruency (retrospective sensorimotor cue) over implicit (intentional binding) and explicit (verbal judgments) SoA. Our results suggest that prospective sensorimotor cues determine implicit SoA. At the explicit level, retrospective sensorimotor cues and contextual cues are partly integrated in an additive way, but contextual cues can also act as a heuristic if sensorimotor cues are highly unreliable. We also found no significant association between implicit and explicit SoA.     

The asymmetric effect of regulatory fit on moral judgments of other-oriented lies

We examined whether regulatory fit effects are asymmetric—namely, whether they occur only among individuals with a promotion focus or a prevention focus. We adopted a task where individuals make moral judgments of other-oriented lies and conducted three studies. The results indicated that prevention-focused individuals judged other-oriented lies based on a vigilant strategy as more moral than lies based on an eager strategy (Studies 1 and 2). Meanwhile for promotion-focused individuals, there were no differences between eager and vigilant strategies on moral judgments of other-oriented lies. Additionally, the results suggested that the feeling of rightness is an underlying mechanism of the regulatory fit effects of prevention focus (Study 3).
