The behavior-therapeutic use of contingency contracting to control an adult behavior problem: weight control

Items considered valuable by the subject and originally his property were surrendered to the researcher and incorporated into a contractual system of prearranged contingencies. Each subject signed a legal contract that prescribed the manner in which he could earn back or permanently lose his valuables. Specifically, a portion of each subject's valuables were returned to him contingent upon both specified weight losses and losing weight at an agreed-upon rate. Furthermore, each subject permanently lost a portion of his valuables contingent upon both specified weight gains and losing weight at a rate below the agreed-upon rate. Single-subject reversal designs were employed to determine the effectiveness of the treatment contingencies. This study demonstrated that items considered valuable by the subject and originally his property, could be used successfully to modify the subject's weight when these items were used procedurally both as reinforcing and as punishing consequences. In addition, a systematic analysis of the contingencies indicated that punishing or aversive consequences presumably were a necessary component of the treatment procedure.     

Speech perception and memory coding in relation to reading ability

Previous work has demonstrated that children who are poor readers have short-term memory deficits in tasks in which the stimuli lend themselves to phonetic coding. The aim of the present study was to explore whether the poor readers' memory dificit may have its origin in perception with the encoding of the stimuli. Three experiments were conducted with third grade good and poor readers. As in earlier experiments, the poor readers were found to perform less well on recall of random word strings and to be less affected by the phonetic characteristics (rhyming or not rhyming) of the items (Experiment 1). In addition, the poor readers produced more errors of transposition (in the nonrhyming strings) than did the good readers, a further indication of the poor readers' problems with memory for order. The subjects were tested on two auditory perception tasks, one employing words (Experiment 2) and the other nonspeech environmental sounds (Experiment 3). Each was presented under two conditions: with a favorable signal-to-noise ratio and with masking. The poor readers made significantly more errors than the good readers when listening to speech in noise, but did not differ in perception of speech without noise or in perception of nonspeech environmental sounds, whether noise-masked or not. Together, the results of the perception studies suggest that poor readers have a perceptual difficulty that is specific to speech. It is suggested that the short-term memory deficits characteristic of poor readers may stem from material-specific problems of perceptual processing.     

Children’s memory for sentences and word strings in relation to reading ability

A previous study of recall of letter strings by good and poor beginning readers IShankweiler, Liberman, Mark, Fowler, & Fischer, 1979 revealed that the performance of good readers was more severely penalized than that of poor readers when the letter names rhymed. To determine whether the differences in susceptibility to phonetic interference extend to materials that more closely resemble actual text, we designed an experiment to test recall of phonetically controlled sentences and word strings. As in the case of letter recall, we found that, although good readers made fewer errors than poor readers when sentences or word strings contained no rhyming words, they did not excel when the materials contained many rhyming words. In contrast to manipulations of phonetic content, systematic manipulations of meaningfulness and variations in syntactic structure did not differentially affect the two reading groups. We conclude that the poor readers’ inferior recall of phonetically nonconfusable sentences, word strings, and letter strings reflects failure to make full use of phonetic coding in working memory.     

The other way around: Effects of causal attributions on estimates of consensus,distinctiveness, and consistency

It was hypothesized that the attributed cause of a given person's behavior will affect inferences about its generalizability over persons (consensus), stimuli (distinctiveness), and circumstances (consistency). Moreover, these effects were expected to parallel the effects of consensus, distinctiveness, and consistency information on causal attributions. Experiment 1 provided support for these predictions but also showed that attribution affected consensus judgments less than it affected judgments of distinctiveness and consistency, particularly when consensus was not the first characteristic estimated. Using a different set of stimulus materials and a different manipulation of attribution, Experiments 2 and 3 provided further evidence for the effects of attribution on inferences of consensus information. Experiment 3 indicated that the false consensus effect—actors' tendency to assume that the majority of people share their behavior—may be due to actors' tendency to attribute their behavior to situational factors. Implications of the present studies for biased estimates of consensus and the use of consensus and attribution as mediating variables are discussed.     

Vicarious and direct counterconditioning of test anxiety through individual and group desensitization

Vicarious and direct desensitization were compared for individual and group treatment of test anxiety. Fifty seventh-graders were assigned by stratified random sampling to the following treatment conditions: direct-individual; vicarious-individual; direct-group; group-observing-group; group-observing-model. Twenty-one eighth-graders served as no-treatment controls. Upon completion of the experimental phase, all subjects were administered a measure of test anxiety and a reading test. As predicted, experimental subjects improved significantly, relative to controls, on both outcome measures; as further expected, the experimental variations did not produce significantly different outcomes among treatment conditions. Neither sex of subject nor assignment to alternative therapists qualified the findings.     

Differences Between Australian and Japanese Students in Reported Use of Decision Processes

Decision making is an activity found in all cultures. Although many theoretical models have been developed to explain human decision making, very few have taken the role of culture into account. In this paper the importance of cultural influences on self-reported decision-making styles is examined, with particular emphasis on the dominant cultural pattern (i.e. “group orientation” versus “individual orientation”). Results of a questionnaire study of 743 Japanese and 309 Australian university students are presented. As predicted, Japanese students reported greater use of decision processes or behaviours associated with the involvement and influence of others (“collateral role”), while Australian students reported greater use of decision processes associated with self-reliance and personal ability (“individual role”).     

The adverse influence of narcissistic injury and perfectionism on college students’ institutional attachment

This study examined the relationship of narcissistic vulnerability, shame-proneness, and perfectionism to college student adjustment. Using a sample of 200 college students, narcissistic injury, socially prescribed perfectionism, other-oriented perfectionism, and self-oriented perfectionism predicted college adjustment as defined as institutional attachment in a canonical correlation analysis. In addition, narcissistic injury, shame-proneness, and socially prescribed perfectionism were found to correlate positively with each other.     

Rapid judgements in assessing verbal and nonverbal cues: their potential for deception researchers and lie detection

In the present study it was investigated to what extent observers (i) could make rapid yet reliable and valid judgements of the frequency of verbal and nonverbal behaviours of interviewees (liars and truth tellers) and (ii) detect deceit after making these rapid judgements. Five observers watched 52 videoclips of 26 liars and 26 truth tellers. The findings revealed that rapid judgements were reliable and valid. They also revealed that observers were able to detect truths and lies well above the level of chance after making these rapid judgements (74% accuracy rate was found). The implications of these findings for deception researchers and lie detection are discussed. Copyright © 2004 John Wiley & Sons, Ltd.
