A comparison of stimulus set size on tact training for children with autism spectrum disorder

Previous studies on skill acquisition have taught targets in stimulus sets composed of different numbers of stimuli. Although the rationale for selection of a stimulus set size is not clear, the number of target stimuli trained within a set is a treatment decision for which there is limited empirical support. The current investigation compared the efficiency of tact training in 4 stimulus set sizes, each of which included 12 stimuli grouped into (a) 4 sets of 3 stimuli, (b) 3 sets of 4 stimuli, (c) 2 sets of 6 stimuli, and (d) 1 set of 12 stimuli. Results of all 4 participants with autism spectrum disorder show tact training with larger (i.e., 6 and 12) stimulus set sizes was more efficient than training with smaller (i.e., 3 and 4) stimulus set sizes.     

Effects of spelling errors on the perception of writers

The authors investigated the perceived relationship between spelling errors and cognitive abilities in a series of 3 experiments. Specifically, they examined whether college students' ratings of an author's intellectual ability, logical ability, and writing ability were affected by the presence of spelling errors. In the 1st experiment, the presence of 4 spelling errors in a short essay did not significantly affect the ratings. The spelling ability of college students, as measured by a standard oral dictation spelling test, was moderately conelated with a brief test of intelligence. In a 2nd experiment, college students rated the author of a short essay as having lower ability when there was a large number of spelling errors. The effect was more pronounced on the ratings of writing ability than it was on the ratings of logical ability or intellectual ability. This finding was replicated in a 3rd experiment, in which the essay contained misspellings actually made by writers. The results suggest that spelling errors can affect how people perceive writers, particularly when there are many spelling errors. College students appear to attribute spelling errors more to writing ability than they do to general cognitive abilities such as intelligence and logical ability.     

A reanalysis of the CARIN theory of conceptual combination

The competition among relations in nominals (CARIN) theory of conceptual combination (C. L. Gagné & E. J. Shoben, 1997) proposes that people interpret nominal compounds by selecting a relation from a pool of competing alternatives and that relation availability is influenced by the frequency with which relations have been previously associated with the modifying concept. The current authors derived relation frequencies by using a sample of compounds occurring in the British National Corpus and compared them with those derived by Gagné and Shoben. The authors demonstrated that the original relation frequencies are unrepresentative and that Gagne' and Shoben's technique for dichotomizing them into high and low is unreliable. In addition, the authors revealed anomalies in the mathematical instantiation of the CARIN model and showed that it does not provide evidence for competition among relations.     

Peer Influence: Mechanisms and Motivations

This research addresses a question that has not been previously – why do youths try to influence their friends’ behavior? Analysis of written accounts of peer influence toward both deviance and conformity reveals clear differences in motives for peer influence toward prosocial and deviant behavior. Influence toward deviant behavior is much more likely to be motivated by selfish concerns, and influence toward prosocial behavior is more likely to be motivated by altruistic concerns. These findings are consistent with the control theory view that crime and deviance is asocial behavior, and not the result of strong social ties to others.     

techniques of neutralization and self-esteem: a critical test of social control and neutralization theory

Sykes and Matza argued that delinquents use techniques of neutralization to enable themselves to engage in behavior they believe is wrong under most circumstances. One function of using these techniques is that the individual is able to protect his or her self-concept while committing delinquent acts. This implies that delinquent youth who use these techniques should have higher levels of self-esteem than delinquents who do not use them. Because Sykes and Matza hold that neutralization is necessary because of the delinquents ties to conventional society, this effect should be stronger among delinquent youth who are more strongly attached to their parents. In contrast, Hirschis social control theory predicts that delinquents who are able to maintain a bond to conventional society should be less likely to neutralize, but if they do neutralize, they should be unable to sufficiently convince themselves of the validity of the neutralizations to protect self-esteem. These hypotheses are tested using data from the Richmond Youth Survey. The results differed depending on whether general neutralizations or neutralizations regarding the police were analyzed. Children who are attached to their parents are less likely to use police-related neutralizations, but delinquents who use these neutralizations have higher self-esteem, consistent with neutralization theory. Delinquents who are more strongly attached to their parents are also less likely to use general neutralizations, but these neutralization techniques do not lead to higher levels of self-esteem, consistent with control theory.     

The role of intergroup disgust in predicting negative outgroup evaluations

We introduce intergroup disgust as an individual difference and contextual manipulation. As an individual difference, intergroup disgust sensitivity (ITG-DS) represents affect-laden revulsion toward social outgroups, incorporating beliefs in stigma transfer and social superiority. Study 1 (5 samples, N = 708) validates the ITG-DS scale. Higher ITG-DS scorers demonstrated greater general disgust sensitivity, disease concerns, authoritarian/conservative ideologies, and negative affect. Greater ITG-DS correlated with stronger outgroup threat perceptions and discrimination, and uniquely predicted negative outgroup attitudes beyond well-established prejudice-predictors. Intergroup disgust was experimentally manipulated in Study 2, exposing participants (n = 164) to a travel blog concerning contact with a disgust-evoking (vs. neutral) outgroup. Manipulated disgust generated negative outgroup evaluations through greater threat and anxiety. This mediation effect was moderated: Those higher (vs. lower) in ITG-DS did not experience stronger disgust, threat, or anxiety reactions, but demonstrated stronger translation of aversive reactions (especially outgroup threat) into negative attitudes. Theory development and treatment implications are considered.     

We don’t like your type around here: Regional and residential differences in exposure to online hate material targeting sexuality

What factors are related to online targeting of hate material based to sexual orientation? This study addresses that question, utilizing a sample of 968 Internet users aged 15–36. Employing a logistic regression analysis, we find that social network usage, online antagonism, informal online social control, and a lack of online anonymity increase the likelihood of being targeted. Moreover, individuals living in the southern region of the United States are nearly three times as likely to be targeted by hate related to sexual orientation, whereas those living in rural areas are more than twice as likely to face such targeting.     

Semantic and subword priming during binocular suppression

In general, stimuli that are familiar and recognizable have an advantage of predominance during binocular rivalry. Recent research has demonstrated that familiar and recognizable stimuli such as upright faces and words in a native language could break interocular suppression faster than their matched controls. In this study, a visible word prime was presented binocularly then replaced by a high-contrast dynamic noise pattern presented to one eye and either a semantically related or unrelated word was introduced to the other eye. We measured how long it took for target words to break from suppression. To investigate word-parts priming, a second experiment also included word pairs that had overlapping subword fragments. Results from both experiments consistently show that semantically related words and words that shared subword fragments were faster to gain dominance compared to unrelated words, suggesting that words, even when interocularly suppressed and invisible, can benefit from semantic and subword priming.     

Experiencing Alien-Nation: Effects of a simulation intervention on attitudes toward homosexuals

The authors explored psychological mechanisms underlying a teaching exercise [Hillman, J., & Martin, R. A. (2002). Lessons about gay and lesbian lives: A spaceship exercise. Teaching of Psychology, 29, 308-311] that may improve attitudes toward homosexuals. Heterosexual participants were randomly assigned to a simulation intervention or control lecture condition. In the simulation condition, participants imagined life on an alien planet that inadvertently simulated situational constraints parallel to those faced by homosexuals. The simulation (vs. control lecture) produced significantly more intergroup perspective-taking, empathy, and favorable attitudes toward homosexuals and marginalized groups. Tests of a structural equation model supported the assumption that the simulation (vs. control) provided an experience that heightened intergroup perspective-taking, which indirectly predicted favorable attitudes via independent cognitive (inclusive intergroup representations) and affective (empathy) paths. The model held after statistically controlling for prior attitudes and ideological individual differences predicting anti-homosexual bias. Implications for prejudice-reduction simulations and intergroup contact are considered.
