A comparison of prompting methods to teach sight words to students with autism spectrum disorder

Time delay procedures are one of the most commonly used and effective strategies for teaching sight words to learners with disabilities. However, less is known about whether they are differentially effective and efficient with learners. This study compared the effectiveness and efficiency of progressive time delay and simultaneous prompting on sight word acquisition among three learners with autism spectrum disorder using an adapted alternating treatments design across word sets. For two participants, both procedures led to skill acquisition with no clear differences in efficiency. For the remaining participant, neither procedure was effective; therefore, the reading task was changed to a receptive one, and a stimulus fading intervention package was implemented.     

The role of money in the excitement of gambling

Many gamblers claim that gambling is intrinsically exciting, with money playing only a secondary role. To examine the effects of the expectancy of winning money, the authors randomly assigned 243 male college student gamblers to 1 of 6 experimental or 1 of 3 control conditions. Control participants either simply watched a videotaped horse race or they picked a horse, but without wagering; that horse later turned out to be either the winner of the race or the runner-up. Experimental participants wagered $1 on a horse for a chance of winning either USD 2, USD 7, or USD 15, with half winning and half losing their wagers. Wagering led to increased heart rates and subjective excitement as a function of the expected payoff and of winning as opposed to losing the wager. The study was replicated with 200 female college student gamblers with similar results. These findings support the notion that the excitement of gambling is tied to the expectancy of winning money.     

Social Identity versus Reference Frame Comparisons: The Moderating Role of Stereotype Endorsement

Two studies tested the prediction that belief in a negative stereotype about an in-group will cause members to shift from viewing their in-group as a social identity to viewing it as a frame of reference. The stereotype that was the focus of inquiry was the belief that women have less aptitude at math and spatial tasks than do men. In both studies, female participants took a test of math and spatial ability and then received social comparison information about their abilities relative to a male and a female confederate. In Study 1, participants felt enhanced when the two women outperformed the male confederate, even when this meant that the participants themselves performed worse than the other woman. If participants were first reminded of the negative stereotype, however, they felt best when they outperformed the other woman, even if this meant that the two women performed worse than the man. Study 2 showed that the effects of stereotype activation were especially pronounced among female participants who showed moderate to high levels of stereotype endorsement. These findings suggest that belief in stereotypes about the in-group can lead to in-group comparison and contrast, even in contexts in which a group member's ability level challenges the validity of the stereotype.     

Notetaking in non‐academic settings: a review

There is considerable research on notetaking in academic settings but relatively little of it in non‐academic ones. This paper reviews the effects of notetaking in legal situations, counselling and interviewing, and assesses the usefulness of notetaking as a memory aid for older people and as a prospective memory device for brain‐injured persons. The results suggest that: notetaking has no significant effect on recall in ‘real‐life’ jury situations; there is some evidence that notetaking by counsellors in counselling sessions might be harmful for clients; there is some evidence that notetaking in interviews can reduce bias in decision making; there is some evidence that notetaking is helpful for older persons; and that too little research has been conducted on the use of notetaking as a device for aiding the prospective memory for brain‐injured persons to reach any firm conclusions. The general limitations of the research are reviewed and implications for future work considered. Copyright © 2002 John Wiley & Sons, Ltd.     

When What You Want is What You Get: Pay Dispersion and Communal Sharing Preference

The question of whether pay structures should be compressed or dispersed remains unanswered. We argue that pay dispersion can yield uncertainty regarding others' intentions and behaviors; as a result, individuals take a greater risk trusting their group members as pay spreads widen. Accordingly, we explore the conditions under which individuals are more willing to take this risk by viewing their group members as trustworthy even when pay is dispersed. Specifically, preferences for how relationships and resources should be structured in groups should help to determine when pay dispersion relates to trustworthiness perceptions. We hypothesise that the cross‐level interaction between preferences for communal sharing (Level 1)—that is, the extent to which individuals prefer communal, egalitarian structures in their groups—and pay dispersion (Level 2) is associated with trust perceptions. Data drawn from a sample of university professors support our hypothesised cross‐level interaction, and show that when pay dispersion is greater, individuals perceive their group members as more trustworthy only when they have weak preferences for communal sharing. Our results signify the importance of individual attributes to understanding pay dispersion's effects, and show that trust is fostered when preferences and pay conditions are aligned.     

Allocation of visual attention in younger and older adults.

Younger and older adults were compared in three experiments, using procedures that had been shown to affect the spread of visual attention. The attentional effects found in previous experiments were replicated. A broader focus of attention speeded responses to peripheral targets. In addition, two established findings concerning aging were replicated: Responses were slower in older than in younger adults, and, in certain conditions, they slowed more rapidly as target eccentricity increased. No interactions of age effects with attentional manipulations were found. The results of all three experiments were consistent with the interpretation that younger and older adults do not differ in the allocation of attention.     

Stimulus complexity, EEG abundance gradients, and detection efficiency in a visual recognition task.

Occipital EEG was monitored while subjects inspected 27 projected patterns. The number (N) and variety (V) of elements in the patterns were varied systematically. There were three levels of N (6, 12 or 24 elements) and three levels of V (circles, squares or hexagons occupying all, one half or one third of the element locations for all levels of N). Subjects were instructed that they would be required in a post-test to recognize the patterns, among patterns which had not appeared; they were also informed that the patterns had been constructed according to a set of simple rules, but the nature of these rules was not made fully explicit. The EEG was quantified by means of low-frequency analysis, yielding measures of abundance (theta, alpha and beta) and mean dominant frequency. For the recognition task, nine stimulus items were embedded among 45 items. Recognition efficiency was measured by means of the signal detection theory discrimination index (d'). The results were as follows: (i) Both N and V were inversely related to alpha abundance (P less than 0-01); (ii) the strongest relationship between stimulus parameters and the EEG held for N and EEG beta activity (13-5-19-5 Hz;P less than 0-001), where again the EEG and N were inversely related; (iii) there was a significant (P less than 0-05) direct relationship between N and theta activity; (iv) contrary to prediction, mean dominant alpha frequency decreased as N increased; (v) d' correlated significantly with a number of effects for N, i.e. subjects who exhibited greatest EEG discriminability of items during exposure of the patterns, subsequently obtained the higher detection scores in the recognition task. The work described therefore demonstrates that only only do stimulus parameters have systematic effects upon brain activity as measured by the EEG, but that such effects have functional value and reflect aspects of efficiency. The results are fully compatible with arousal theory constructs relating physiological reactivity and performance.     

Relative competence,reinforcement and conformity

Forty male inmates from an adult correctional training centre participated in a 2 × 2 factorial design with subject correctness-incorrectness and group agreement-disagreement constituting the classification factors. A modified Asch procedure was used to manipulate a S's prior experience of correctness and agreement (Part 1) and to assess subsequent conformity to 3 male confederates (Part 2). The female experimenter served as the source of reinforcement and group correctness. Ss responded to a (two part) 26 verbal and perceptual item scale, including 11 conformity items. Subject correctness and group agreement interacted, for perceptual items only, so that subjects who were more competent than the group or equally incompetent to the group conformed less than those who were less competent than the group, who in turn conformed less than those who were equally competent to the group, where both the subjects and the group were correct. Subjects conformed more to difficult verbal items than to perceptual items, and unsuspicious subjects conformed more than suspicious subjects. Both relative competence, mediating the effects of prior experience, and the situational factor of reinforcement affect conformity to perceptual tasks.
