Studies of the Startle Pattern: IV. Infants

Individual versus group risk taking was examined by using a novel set of industrial product purchasing situations as stimuli. The set incorporated situations that varied along a dimension called “normative risk.” Situations represented either low-normative risk, medium-normative risk, or high-normative risk. Normative risk was defined in a decision theoretical context. The set was administered to introductory business students at a large university in the United States. The results of the study showed that groups were not invariably riskier than individuals; rather the amount of risky shift following group discussion was negatively related to the level of normative risk. This overall conclusion held true also in relation to the degree of perceived riskiness of the situations, since a positive relationship between normative risk and perceived risk was established. The theoretical implications of the results are discussed.     

Using Potential Performance Theory to Test Five Hypotheses About Meta-Attribution

The aim of this study was to compare the reaction times and errors of Spanish children with developmental dyslexia to the reaction times and errors of readers without dyslexia on a masked lexical decision task with identity or repetition priming. A priming paradigm was used to study the role of the lexical deficit in dyslexic children, manipulating the frequency and length of the words, with a short Stimulus Onset Asynchrony (SOA = 150 ms) and degraded stimuli. The sample consisted of 80 participants from 9 to 14 years old, divided equally into a group with a developmental dyslexia diagnosis and a control group without dyslexia. Results show that identity priming is higher in control children (133 ms) than in dyslexic children (55 ms). Thus, the “frequency” and “word length” variables are not the source or origin of this reduction in identity priming reaction times in children with developmental dyslexia compared to control children.     

Frankfurt cases and the (in)significance of timing: a defense of the buffering strategy

Frankfurt cases are purported counterexamples to the Principle of Alternative Possibilities, which implies that we are not morally responsible for unavoidable actions. A major permutation of the counterexample strategy features buffered alternatives; this permutation is designed to overcome an influential defense of the Principle of Alternative Possibilities. Here we defend the buffering strategy against two recent objections, both of which stress the timing of an agent’s decision. We argue that attributions of moral responsibility aren’t time-sensitive in the way the objectors suppose. We then turn to the crucial question of when an action is relevantly avoidable—when, in the parlance of the literature, an alternative possibility is robust. We call attention to two plausible tests for robustness that merit further consideration, showing that the agents in buffered Frankfurt cases don’t pass these tests, despite being morally responsible for their actions.     

Information‐Seeking Behavior in Intercultural and Intergroup Communication

This review essay analyzes the current status of information‐seeking research and theory in the field of intercultural communication writ broadly. After drawing distinctions between different types of intercultural communication research (cross‐cultural, intercultural, intergroup), the authors discuss how information seeking might be relevant across types and different between types of intercultural communication. Finally, the authors recommend directions for future research.     

The celebrity appeal questionnaire: sex, entertainment, or leadership

The Celebrity Appeal Questionnaire was constructed to operationalize constructs related to why fans are attracted to their favorite celebrities and was developed for use with fan bases for specific celebrities. This revised version asked fans of a specific celebrity to rank order three roles they might see the target celebrity playing in society with an option to not rank them at all. Of 409 respondents attending Josh Groban fan club meetings, 75% said Groban's most important role in society was as a leader and role model in trying to make the world a better place. A factor analysis of correlations of Likert-type scale ratings and an analysis relating those factors back to the rank orderings support the internal reliability and validity of the questionnaire.     

RT distribution analysis of category congruence effects with masked primes

Macquarie University, Sydney, New South Wales, Australia In the number magnitude decision task (“Is the number bigger/smaller than 5?”), response to a target (e.g., 3) is faster following a masked prime congruent with the target (e.g., 1) than it is following an incongruent prime (e.g., 9). This category congruence effect has been reported to be “interference-dominant” relative to a neutral prime (e.g., the # sign, the number 5) on the basis of the analysis of mean response time (RT). Using RT distribution analysis as well as mean RTs, we identified two bases for this pattern. One relates to the choice of neutral baseline: The # prime, unlike the digit prime, does not factor in the cost of perceptual transition between the prime and target, and therefore underestimates facilitation and overestimates the interference effect. The second basis of the interference-dominant pattern is a disproportionate slowdown of congruent trials in the slow RT bins. Furthermore, this slowdown is greater for primes that had been used as targets than it is with “novel” primes that have not been responded to as targets. We interpret the results as suggesting that the category congruence effect has two components with different time courses—one based on stimulus-response mapping, and the other on semantic categorization.
