Onsets and rimes as units of spoken syllables: evidence from children

The effects of syllable structure on the development of phonemic analysis and reading skills were examined in four experiments. The experiments were motivated by theories that syllables consist of an onset (initial consonant or cluster) and a rime (vowel and any following consonants). Experiment 1 provided behavioral support for the syllable structure model by showing that 8-year-olds more easily learned word games that treated onsets and rimes as units than games that did not. Further support for the cohesiveness of the onset came from Experiments 2 and 3, which found that 4- and 5-year-olds less easily recognized a spoken or printed consonant target when it was the first phoneme of a cluster than when it was a singleton. Experiment 4 extended these results to printed words by showing that consonant-consonant-vowel nonsense syllables were more difficult for beginning readers to decode than consonant-vowel-consonant syllables.     

Effects of wage inequities on work attitudes and performance

A replication and extension of the Adams and Jacobsen (1964) investigation of inequity theory was carried out using a 3 × 2 experimental design with three levels of compensation and two levels of qualifiedness. This design included an overcompensated condition in which the overpayment was not confounded with unqualifiedness, thereby allowing a comparison of differential predictions from inequity and expectancy theory. Comparisons of over and underpayment conditions were also made to test the differential threshold hypothesis of inequity theory. Attitudinal as well as performance data were collected to investigate the possibility of differing modes of inequity reduction.The major finding in the present study was that variations in manipulated perceptions of qualifiedness produced significant effects upon both quality and quantity measures of work behavior while induced variations in the amount of anticipated compensation only affected quality of work. The qualified conditions produced fewer pieces of higher quality. This finding was discussed from the point of view of inequity theory as well as an alternative “self-esteem” explanation.Differences in work performance across pay levels were nonsignificant with the exception of a work quality measure in which the overpaid qualified group produced significantly more errors than the standard pay-qualified group. Possible interpretations of these findings were discussed and a range of conditions which may affect perceptions of inequity were considered.     

Role of intertrial interval following an escape or avoidance response in bar-press avoidance

In three experiments, rats learned bar-press avoidance as a function of the intertrial interval following an escape or an avoidance. The general hypothesis is that the length of these intervals affects bar-press avoidance differentially, depending on whether an avoidance follows an escape (avoidance/escape) or an avoidance (avoidance/avoidance) on the previous trial. Specifically, it is proposed that short escape ITIs will facilitate avoidance/escape and avoidance/avoidance, while avoidance ITIs will have no effect on avoidance responding. The results tend to support this hypothesis. The shorter the intertrial interval following an escape, the higher the probability of both measures: avoidance/escape and avoidance/avoidance. No effect of avoidance interval was found on avoidance/avoidance. Unpredictedly, however, it was found that in comparison to a very short intertrial interval following an avoidance (0.5 sec), relatively long intervals (5 and 45 sec) facilitate avoidance/escape. These results were interpreted as mainly reflecting nonassociative factors such as shock-produced activity.     

Acquired and developmental spelling dyslexia

Two cases of acquired spelling dyslexia and one case of developmental spelling dyslexia are described along with accounts of their performance on various psycholinguistic tasks. It is argued that there is some evidence that spelling dyslexia may exist in developmental form but that parallels are difficult to draw because of the very different histories of child and adult cases. It is also suggested that features of surface dyslexia exist in at least a proportion of spelling dyslexic cases and that this may be influenced by level of premorbid reading skill.     

Gradients of attraction as a function of the fit between social setting and stimulus person characteristics: Studies of the differentiation of attitude

Two experiments compared three alternative hypotheses concerning differences in attraction to a person across interaction settings: A compartmentalization hypothesis assumes that a person's (A's) intimate and nonintimate characteristics only affect attraction to him in intimate and nonintimate interactions, respectively, and that there is no generalization of attraction across levels of intimacy. An intimacy dominance hypothesis assumes that a person's intimacy-related characteristics determine attraction to him at all levels of interaction. Finally, an intimacy threshold hypothesis assumes that a person's intimacy-related characteristics become increasingly relevant to attraction as the intimacy of interaction increases, but that these characteristics need not influence attraction at nonintimate levels of interaction. Experiment 1 supported the compartmentalization hypothesis. Attraction to a formal teacher decreased as the intimacy of the anticipated setting increased, while attraction to an informal teacher increased with increasing setting intimacy. In Experiment 2, agreement on intimate topics promoted liking for a peer while no effect was found for agreement on superficial topics. This effect only emerged for intimate interaction settings, supporting the intimacy threshold hypothesis. High positive correlations between distance preference and attraction were obtained in Experiment 1, while analogous data obtained in Experiment 2 had less clear implications.     

Development of natural language concepts: IV. The relationship between semantic organization and learning

In Experiment 1, 30 subjects at each of three age levels were shown pictures of unfamiliar “animals”. They were told two semantic attributes for each animal (e.g., kind and strong) and were asked to learn these sets so that, when shown a picture, the appropriate attributes could be recalled. The results indicated that the dimensional structure of the attributes had a strong effect on new learning for young children. Incongruent pairs of attributes (e.g., kind and ugly) were difficult to learn compared to congruent (e.g., kind and beautiful) or unrelated (e.g., kind and tall) sets. These results indicate: (a) Attribute structure is a factor in new learning; (b) 6-year-olds tend to organize the verbal labels for attributes into bipolar dimensions, rather than into independent clusters of attributes. The latter findings require reexamination of the meaning of previous word-association data which had been interpreted as indicating that 6-year-olds tend not to organize meanings bipolarly. Experiment 2 showed that the disruptive effects of incongruence on new learning disappears by college age.     

Let's pretend: The role of motoric imagery in memory for sentences and words

A number of theories suggest that for young children, concepts should have an important motoric (or sensory-motor) component. A levels-of-processing theory is proposed which predicts that processing on motoric imagery should facilitate memory for both isolated words and for sentences. Experiment 1 examined the effects of motoric enactment (viz., pretend play) of sentences on memory for the sentences. Motoric imagery facilitated memory for both children (5 to 7 years of age) and adults, though, contrary to expectations, the effects were weaker for the children than for the adults. Further, it was found that motoric imagery affected the initial acquisition, but was not important as a retreival cue. Experiment 2 examined the effects of motoric imagery on free recall of lists of unrelated words. Under these conditions, motoric imagery facilitated memory for both children (7 to 9 years of age) and adults equally; in contrast, visual imagery instructions had no effect on memory. These results indicate that motoric imagery may facilitate memory under conditions in which visual imagery has no effect. Theoretical implications are explored for previous experiments on pretend play which suggest that training for pretent enactment can facilitate cognitive development.     

Toward quality criteria for collective judgments

While most organizational and social decision making is done in a group or collective mode, there are few guides or evaluative criteria for judging when a high-quality outcome has been reached. Most past studies of group decision making have been conducted in laboratories using student subjects and factual problems with correct answers as means for judging outcome quality. Such proxies are rough approximations at best of real-world conditions where value differences can be intense and problems have no correct or best answer. Drawing upon the existing literature, evaluative criteria are proposed including process, content, and outcome concerns. An instrument based upon these criteria is then applied retrospectively to six cases of ad hoc collective decision making. Using dimensional analyses, a set of more detailed evaluative factors is derived from actual participant responses. The results provide some insights into the nature of high-quality collective judgments as well as the most effective procedures for their achievement.     

Moral judgment and attitudes toward authority of political resisters

In an exploration of the personal basis of resistance to authority, moral judgment and attitudes toward authority were examined in 183 men and women political resisters, including antinuclear, draft registration, and tax resisters, and anarchists, and compared to 34 liberal and 29 conservative activists. The measures used were the Defining Issues Test and a specially designed attitude survey. As predicted, the differences between resisters and nonresisters were in the realm of cognitive beliefs and values. Strong rejection of political and social authority, a belief that individual conscience is a better guide to conduct than the law, a professed unwillingness to be in positions of authority over others, and a lack of conventional religious affiliation significantly differentiated the resisters from the nonresisters. The resisters also measured high in level of moral judgment but were significantly different only from the conservatives.     

Cognitive strategies in a complex judgment task: Analyses of concurrent verbal reports and judgments of cumulated risk over different exposure times

Subjects judged the cumulated risk of dying during a year for a set of persons or cases each characterized by the risks during three different periods of risk exposure during the year (e.g., 18 weeks with 2.3 deaths per thousand persons per year of exposure, 28 weeks with 2.5 deaths and 6 weeks with 16.0 deaths per thousand per year). Three main strategies were used for solving the problems: (1) addition of the risk levels, (2) computing the mean of the risk levels, and (3) the most frequently used anchoring and adjustment strategy most closely approximating the normatively correct risk over the year. The first two strategies do not use all relevant information because they neglect the importance of different exposure times. The anchoring and adjustment strategy used all information and was executed in a first stage in which an initial anchor or reference risk was selected followed by a second stage in which this anchor was adjusted according to the remaining information. The process for finding the first anchor was quite flexible, using different principles (e.g., extreme values or similarity) depending on the pattern of cues characterizing each case. Biases in relation to normative theory originated from subjects misunderstanding or simplifying the problem (Strategies (1) and (2)) or the characteristics of the anchoring and adjustment process which resulted in relative overestimation of short-time, high-risk cases. A few subjects, however, all of whom used sequential anchoring and adjustment, succeeded in giving quite accurate estimates.     

Cognitive dissonance and psychotherapy: The role of effort justification in inducing weight loss

The role of effort justification in psychotherapy was examined. It was hypothesized that the effort involved in therapy, plus the conscious decision to undergo that effort, leads to positive therapeutic changes through the reduction of cognitive dissonance. An experiment was conducted in which overweight subjects attempted to lose weight through one of two forms of “effort therapy”. These therapies were bogus in that they were based solely on the expenditure of effort on a series of cognitive tasks that were unrelated to any existing techniques or theory addressing weight loss. One of the therapies called for a high degree of effort while the degree of effort in the second therapy was low. A no-treatment control group was also included. It was predicted that greater weight loss would occur for high-effort than low-effort or control subjects, and that this weight loss would be maintained or increased over time. Results supported these predictions. Over an initial 3-week period, high-effort subjects lost slightly more weight than low-effort subjects or controls. A 6-month follow-up revealed that the effects of effort on weight loss had increased and were highly significant. Reliable differences remained even 1 year after the initial experimental sessions. Possible mechanisms mediating the dissonance effect were discussed, as were several alternative explanations.     

What the classical aphasia categories can't do for us, and why

A good deal of activity in contemporary aphasia research goes under the label "neurolinguistics." What characterizes this enterprise is, among other things, its goal of identifying neurally realized computational subsystems that support language processing. In this essay the thesis is put forward that this goal will not be served by the continued exploitation of the classical (Wernicke-Lichtheim) taxonomic categories. These categories, it is argued, cannot by virtue of their "polytypic" structure support the relevant neurolinguistic generalizations.     

Phonemic imperception in aphasia

This study investigated characteristics of 14 aphasics with impaired phoneme discrimination identified from a population of 100 patients with left hemisphere lesions. All patients with impaired phoneme discrimination were significantly impaired in aural comprehension, but many showed intact sound recognition and some showed normal reading comprehension. Defects in phoneme discrimination were typically seen in the acute stage of aphasia resulting from stroke; and in most instances, defects in phoneme discrimination were no longer apparent 4 months postonset. All patients who recovered normal phoneme discrimination also made significant improvement in aural comprehension. The findings support the concept that some aural comprehension defects result from a specific disturbance in phoneme discrimination.     

Children's cultural values and parental child rearing strategies

Researchers during the past 40 years have infrequently disentangled the relationship between young black children's personal identity and group identity, generally treating them in an undifferentiated manner. Investigators suggest that impersonal agents determine young black children's white-biased cultural values, usually ignoring the influence of parental child-rearing strategies. Findings from three studies in the Midwest, North, and South document that preschool children show consistently Eurocentric (white-biased) choice behavior; the trend for most attitudes and preferences changes to an Afrocentric orientation during middle childhood. Parental interviews obtained from a subsample of Southern parents offer alternative interpretations of these choice patterns; values transmitted (e.g., teaching children about civil rights and racial discrimination) predict children's Afrocentric racial attitudes and preferences.     

The effects of word class on children's reading and spelling

Children's oral language functioning has been shown to be affected by word class (i.e., content vs. noncontent words). The present study reveals comparable effects on children's written language performance. In spelling and reading, third and fifth graders show faster and more accurate responses to nouns and verbs than to noncontent words of matched length and frequency. Further, when the children's performance is examined in relation to level of reading skill, it is found that the less-skilled readers exhibit a greater content/noncontent differential than do the more skilled readers. The results are discussed with reference to differential access for the two word classes and its implication for both oral and written language functioning.     

The effect of standard, motivation, and strategy instructions on the facial processing accuracy of internal and external subjects

In the present study, it was hypothesized that poorer performance of externals in cognitive and interpersonal tasks also would be found in the processing of nonverbal information in the form of a facial affect recognition task. It was further hypothesized that the poorer nonverbal processing performance of externals was due to either their lower motivation or their use of less effective processing strategies. Subjects (N = 70) were divided into internal and external groups and then further subdivided into groups that received standard, motivational, or strategy instructions. Analysis of subjects' responses to the facial affect recognition task showed internals performed significantly better than externals under standard conditions. However, neither motivational nor strategy instructions improved the performance of externals. The implications for interpersonal functioning of the poorer nonverbal processing ability of extenrals was discussed from both theoretical and methodological perspectives.     

Reinforcement and punishment in a closed system

Children chose between toys freely and with various restrictive contingencies. Sometimes play with a preferred toy was contingent on play with a nonpreferred toy. Sometimes play with a nonpreferred toy was contingent on play with a preferred toy. Another toy (free toy) was always available during contingency sessions. Because toy playing occupied the entire session the response system was closed. When one response increased in duration others had to decrease. An analysis of closed-system responding revealed that the restrictions of the closed system together with the restrictions imposed by the contingencies forced subjects to alter the proportion of time devoted to the three responses. A geometrical model representing the closed system and an analytical method based on distance are presented to describe the data.     

Cognitive biases in blaming the victim

Past research on cognitive biases has demonstrated the existence of a hindsight effect, whereby the receipt of outcome knowledge increases the perceived likelihood of the reported event. Three experiments were conducted that tested and supported the hindsight effect as a cause of victim blaming. Subjects read detailed accounts that were identical except for the concluding sentence, which provided outcome information. Half the subjects in each experiment were informed that the woman narrating the account was raped; the other half read a neutral outcome. Experiment 1 demonstrated that subjects were unable to ignore the influence of outcome knowledge, leading to an exaggerated perception of how likely the outcome appeared. In Experiment 2, the woman was blamed more by subjects who read the rape outcome than by those who read the neutral outcome, despite the presentation of identical behaviors and personality traits prior to outcome information. The increased blame attributed by rape outcome subjects was behavioral, and not characterological, in nature. Experiment 3 found a direct association between the hindsight effect and victim blaming and also demonstrated that an attempt to reduce the negative impact of the hindsight effect on victim blaming was ineffective due to the salience of the rape outcome. Explaining how a neutral outcome was possible given the same account did not reduce victim blaming by subjects who received a rape outcome. Rather, those who received a neutral outcome increased their victim blaming when asked to explain a rape outcome. The implications for victims are discussed.
