A PRP-study to determine the locus of target priming effects

Visual stimuli that are made invisible by a following mask can nonetheless affect motor responses. To localize the origin of these target priming effects we used the psychological refractory period paradigm. Participants classified tones as high or low, and responded to the position of a visual target that was preceded by a prime. The stimulus onset asynchrony (SOA) between both tasks varied. In Experiment 1 the tone task was followed by the position task and SOA dependent target priming effects were observed. When the visual position task preceded the tone task in Experiment 2, with short SOA the priming effect propagated entirely to the tone task yielding faster responses to tones on visually congruent trials and delayed responses to tones on visually incongruent trials. Together, results suggest that target priming effects arise from processing before and at the level of the central bottleneck such as sensory analysis and response selection.     

Referential competence is associated with motivational congruence

[Schultheiss, 2001] and [Schultheiss, 2008] hypothesized that referential competence (RC) - stable individual differences in the ability to quickly name nonverbally represented information - should predict congruence between implicit and explicit motives. We tested this hypothesis using a color-naming task to assess RC, picture-story measures of implicit motives, and self-report measures of participants’ motivational values and goals. Study 1 showed that the RC measure captures a stable individual difference by test-retest and internal consistency criteria. Studies 2 and 3 provided correlational evidence for the hypothesized association between RC and measures of between- and within-individual motivational congruence. Study 4 showed that in the absence of situationally induced referential processing, RC predicts preferences for motive-congruent goals.     

Creative production by angry people peaks early on, decreases over time, and is relatively unstructured

Anecdotes and introspective reports from eminent scientists and artists aside, a systematic test of the putative creativity-enhancing effect of anger is missing. This article fills this void with three experiments examining creativity as a function of anger (vs. sad or a mood-neutral control state). Combining insights from the literatures on creativity and on mood and information processing the authors predicted that anger (vs. sadness and a mood-neutral control state) triggers a less systematic and structured approach to the creativity task, and leads to initially higher levels of creativity (as manifested in original ideation and creative insights). Following work on resource depletion, the authors further predicted that anger more than sadness depletes resources and that, therefore, creative performance should decline over time more for angry than for sad people. Results supported predictions. Implications for creativity, information processing, and resource depletion are discussed.     

Shaping reality vs. hiding from reality: Reconsidering the effects of trait need for closure on information search

For tentative and final decisions on real and artificial issues, three studies revealed a positive relation between trait need for closure and selective approach to supportive (vs. unsupportive) information. Specifically, individuals with high (vs. low) trait need for closure selected more decision-supportive information and less decision-challenging information for viewing. Furthermore, Study 1 showed that the effect of trait need for closure functioned independently of authoritarianism and dogmatism, and Study 3 showed that the effect of trait need for closure on selective approach to decision-supportive information was mediated by a current concern to get closure on the experimental issue. These findings provide a new understanding of how trait need for closure shapes post-decisional information search and decision making.     

Prominence vs. aboutness in sequencing: A functional distinction within the left inferior frontal gyrus

Prior research on the neural bases of syntactic comprehension suggests that activation in the left inferior frontal gyrus (lIFG) correlates with the processing of word order variations. However, there are inconsistencies with respect to the specific subregion within the IFG that is implicated by these findings: the pars opercularis or the pars triangularis. Here, we examined the hypothesis that the dissociation between pars opercularis and pars triangularis activation may reflect functional differences between clause-medial and clause-initial word order permutations, respectively. To this end, we directly compared clause-medial and clause-initial object-before-subject orders in German in a within-participants, event-related fMRI design. Our results showed increased activation for object-initial sentences in a bilateral network of frontal, temporal and subcortical regions. Within the lIFG, posterior and inferior subregions showed only a main effect of word order, whereas more anterior and superior subregions showed effects of word order and sentence type, with higher activation for sentences with an argument in the clause-initial position. These findings are interpreted as evidence for a functional gradation of sequence processing within the left IFG: posterior subportions correlate with argument prominence-based (local) aspects of sequencing, while anterior subportions correlate with aboutness-based aspects of sequencing, which are crucial in linking the current sentence to the wider discourse. This proposal appears compatible with more general hypotheses about information processing gradients in prefrontal cortex (Koechlin & Summerfield, 2007).     

The impact of risk and affect on information search efficiency

We develop and test a theoretical framework of the joint influence of risk and affect on information search efficiency. Our framework proposes that information search is less efficient (i.e., less strategic) when risk is high, versus low. It further proposes that the influences of positive and negative affect on search efficiency are asymmetric and depend on the level of risk. Negative affect improves search efficiency when risk is high, but not when it is low. Positive affect degrades search efficiency when risk is low, but not when it is high. We find results consistent with our framework in two experiments. We discuss implications for affect research and for decision making in risky contexts, including financial statement auditing.     

Commitment to a developing preference and predecisional distortion of information

People tend to distort their evaluation of decision-relevant information in favor of the currently preferred alternative. We test whether this predecisional distortion of information is amplified by increased commitment to that current preference. We manipulated commitment, without changing the preferred option’s content, by requiring participants to indicate their preference either by circling or by darkening a sizable box (cf. feature-positive effect). Experiment 1 revealed that the effort to darken substantially increased predecisional distortion. Experiment 2 ruled out elaboration as an explanation for the effect of darkening. Experiment 3 showed that, among participants who attributed the darkening effort to an external source, predecisional distortion decreased when the source was believed to summon effort. These findings suggest that the developing commitment to a tentatively preferred alternative is one driver of predecisional distortion.     

Consumers' implicit theories about personality influence their brand personality judgments

Three studies document that consumers' implicit theories about the fixedness/malleability of personality guide brand personality updating in a brand extension context. The first two studies show that extension fit with the parent brand impacts brand personality updating only for incremental (vs. entity theorists). Specifically, for incremental theorists, brand personality is enhanced (vs. diluted) when extension fit is poor (vs. good), and only when brand personality is salient. The third study identifies conditions under which entity theorists focus on brand personality. Interestingly, overall evaluations of the parent brand and extension vary only with extension fit. Implications of our research are discussed.     

复述、提取抑制与有意遗忘的实验研究

有意遗忘是关于记忆研究的另一种实验范式,对于在实验中出现的要求遗忘的学习项目的记忆成绩差于要求记忆的项目的结果,目前主人存在着两种理论解释：基于编码的理论和基于提取抑制的理论。该实验运用单字提示方式,采用控制较为严密的补笔测验方法和加入所谓的“无关项”,对有意遗忘的心理过程进行进一步的探讨,实验表明：在单了提示方式下,被试在进行有意遗忘的过程中,既对记忆项进行了有意的复述又对遗忘项产生了提取抑制。
