Attentional SNARC: there's something special about numbers (let us count the ways)

We report a study that examines whether the presentation of irrelevant, ordinal information at central fixation interacts with the allocation of attention beyond fixation. Previous research has demonstrated that number perception influences the allocation of spatial attention, such that the presentation of a spatially nonpredictive number at fixation results in attention being allocated to the left when the central number is low (e.g., 1), and attention being allocated to the right when the central number is high (e.g., 9). Here, we examine whether this attentional SNARC effect (spatial numerical association of response codes) generalizes to other ordinal sequences: letters, days, and months. Though we replicate the attentional SNARC we find that this effect is number-specific, unless participants are required to process the cue in an order-relevant fashion. This discovery of number-specificity has important implications both for the functional separation between SNARC and attention-SNARC effects, as well as lending support to recent theories regarding the specificity of a shared neural architecture between numbers and visuospatial attention.     

Less power or powerless? Egocentric empathy gaps and the irony of having little versus no power in social decision making

The authors investigate the effect of power differences and associated expectations in social decision making. Using a modified ultimatum game, the authors show that allocators lower their offers to recipients when the power difference shifts in favor of the allocator. Remarkably, however, when recipients are completely powerless, offers increase. This effect is mediated by a change in framing of the situation: When the opponent is without power, feelings of social responsibility are evoked. On the recipient side, the authors show that recipients do not anticipate these higher outcomes resulting from powerlessness. They prefer more power over less, expecting higher outcomes when they are more powerful, especially when less power entails powerlessness. Results are discussed in relation to empathy gaps and social responsibility.     

Criterion‐Related Validity of Dutch Police‐Selection Measures and Differences Between Ethnic Groups

This study investigated the criterion‐related validity of cognitive ability as well as non‐cognitive ability measures and differences between ethnic majority (N=2365) and minority applicants (N=682) in Dutch police officer selection. Findings confirmed the relatively low predictive validity of cognitive ability generally found for police jobs. Previous research reported no differential prediction. The present study, however, found small but systematic evidence for differences in validity for the ethnic majority and minority group of both cognitive and non‐cognitive measures. For the minority group, training performance appeared to be mainly predicted by the cognitive ability test. For the majority group, cognitive ability showed very little predictive power. Non‐cognitive ability variables appeared to be somewhat more predictive in this group.     

Acquisition of dispositional attributions: effects of sample size and covariation

Two experiments examined whether dispositional attributions are sensitive to the sample size of the evidence indicating a given level of covariation between person and behavior. Participants were given high or low levels of covariation (i.e. consensus and distinctiveness), and the acquisition of dispositional attributions was monitored by requesting dispositional trait ratings at fixed intervals. The results showed that dispositional attributions were sensitive to sample size, and increased given more evidence on high person‐behavior covariation while they decreased given more evidence on low person‐behavior covariation. Additional analyses suggested that in making dispositional inferences (e.g. about the actor), there was a slight preference for agreement information (e.g. low distinctiveness) over difference information (e.g. low consensus). The effects of sample size are inconsistent with current statistical or probabilistic models of covariation, but are in line with connectionist networks using an error‐correcting learning algorithm.

Rare male aggression directed toward females in a female‐dominated society: Baiting behavior in the spotted hyena

Spotted hyenas (Crocuta crocuta) are gregarious carnivores. The females are socially dominant to males, and adult males rarely direct aggression toward adult females. This study analyzed all cases in which adult immigrant males behaved aggressively toward adult females in a large population of free‐living hyenas in Kenya, observed for 11 years. Our goals were to describe the conditions under which male attacks on females occur, and address possible adaptive functions. Most aggression directed by adult immigrant males against females occurred when coalitions of two or more males attacked a single adult female, who typically responded by defending herself and fighting back. Male aggression against females frequently occurred at sites of ungulate kills, but males never behaved aggressively toward females over food, and all male attacks on females were unprovoked. Although no mounting or other copulatory behaviors ever occurred during or immediately after an attack, the number of male attacks on females peaked around the time of conception. Daily rates at which males attacked females did not vary with female social rank. However, daily attack rates did vary significantly with female reproductive state, and the highest rates of male attack on females were observed during the two stages of the reproductive cycle during which females were most likely to conceive litters. The adaptive significance of male aggression against females in this species remains unknown, but a tight association between male attacks on females and a female's time of conception provides strong evidence of some role for male aggression in hyena sexual behavior. In particular, our data are consistent with hypotheses suggesting that male aggression toward females in this species either serves to inform females about male fitness or represents sexual harassment.

The Measurement of Cognitive Complexity and Its Relationship With Political Extremism

Three studies tested the relationship between political extremism and cognitive complexity in an adult sample (N = 135), a sample of students (N = 145), and a sample of political party members (N = 47). According to value pluralism theory, advocates of extreme ideologies exhibit low levels of cognitive complexity. Context theory, in contrast, states that extremists think in a more complex and sophisticated way about politics. In accordance with context theory, significant positive correlations between cognitive complexity and extremist ideology were found in all samples. The results of these studies also revealed weak correlations among the cognitive complexity instruments used in previous research. Problems concerning the measurement of cognitive style and cognitive complexity are discussed.     

Continuation of exchange with neighbors in later life: The importance of the neighborhood context

Relationships with neighbors are considered exchange relationships, in which the continuation of exchanges depends on balance in previous exchanges. Our study tested whether this is the case. An exchange relationship implies that neighbor relationships are isolated units. We expected, however, that neighborhood integration also affects the continuation of exchange among neighbors. Data were from a longitudinal study among 1,692 independently living Dutch adults of ages 55 to 85 years at baseline and their 7,415 relationships with proximate network members. At a four–year follow–up, both perceived balance and neighborhood integration at baseline increased the chance of instrumental support exchange occurring. We concluded that it is too limited to view relationships between neighbors as exchange relationships, as these relationships are embedded in larger communities, where such communities exist.     

Self–other and third‐person categorization in normal and autistic children

Social information processing has been found to vary as a function of whether perceivers categorize individuals in terms of self and other (SO‐categorization) or using categories associated with the third pronominal person (3P‐categorization). Normal children aged 3–8, autistic children aged 5–9 and adult students were presented with decision tasks that enabled us to assess the use of SO‐ and 3P‐categorizations. A breakthrough of the SO‐categorization was observed at age 5. The hypothesis that 3P‐categorization precedes SO‐categorization was strongly disconfirmed, only adults showing consistent 3P‐categorization. Although previous research suggested a strong association between SO‐categorization and ‘I–Thou’ related social understanding, performances of autistic children suggested that impaired understanding of mental life does not detract from the ability to use SO‐categorization.     

On the psychology of procedural justice: reactions to procedures of ingroup vs. outgroup authorities

Theorizing on procedural justice has assumed that people's reactions to outgroup authorities are to a large extent based on instrumental concerns. Therefore, attention is primarily directed to outcomes rather than procedures in encounters with outgroup authorities. In the current article we propose that in order for people dealing with outgroup authorities to be strongly affected by procedural fairness, the available outcome information should be ambiguous. Furthermore, we argue that people confronted with an outgroup authority react particularly negatively to unfair procedures that give them negative outcome expectancies. These patterns are not expected in encounters with ingroup authorities. Two experiments support our line of reasoning. The discussion focuses on the implications of these findings for the integration of theoretical perspectives on procedural justice. Copyright © 2004 John Wiley & Sons, Ltd.     

Determinants of a Negotiator's Initial Opening Offer

Although the initial offer is a crucial aspect in the process of most negotiations, there is still a complete lack of empirical evidence on what underpins initial offer decisions. For this reason, the effects of different reference points on the negotiator's initial offer were examined in this study. Results from a sample of 596 managers indicate that knowledge of the opponent's best available alternative, or (Best Alternative To a Negotiated Agreement BATNA), is by far the strongest determinant. Criteria of fairness, as reflected in an estimated market price, are also important. However, awareness of the dependency of the other party has no direct effect on the initial offer. Apparently, negotiators define the negotiation game as the management of interdependency in an extremely egocentric way and base their opening offers largely on cues regarding the power structure within the dyad.
