Word frequency and children's stuttering: The relationship to sentence structure

This study investigated the relationship between word-frequency level and stuttering within the context of four slected sentence types. Fifteen stuttering children, aged 8–12, read 48 sentences of four different transformational types, and three word-frequency levels 12 simple active-affirmative-declarative (SAAD), 12 negative, 12 passive and 12 negative-passive. All sentences were identical in terms of underlying swings and variations of the SAAD sentences. Results agreed with Ronson's study with adults (1976) in that when the group rating was severe and the sentence type was negative, stuttering increased significantly as word-frequency level decreased. It appears that children's stuttering in relationship to word-frequency level is a different response that is subject to variables of sentence type and the severity rating of stuttering.     

Internal standards revisited: Effects of social comparisons and expectancies on judgments of fairness and satisfaction

Two studies examined the effect of two comparison processes on perceptions of fairness and satisfaction. Rewards relative to others (social comparison) and relative to expectancies (expectancy comparison) were orthogonally varied while absolute level of reward was held constant. Both studies showed, contrary to previous theory, that only social comparisons are related to perceived fairness, yet both comparisons are significantly related to satisfaction in an additive manner. Social comparisons explained more variation in satisfaction and dominated responses to more specific measures of affect. Partial support for specific predictions derived from equity theory and expectancy theory are reported. The overall results are interpreted as demonstrating the importance of the salience of frames of reference in reward evaluation.Estabilished practices create expectations, and since men have traditionally received greater rewards than women for the same services, they expect disproportionate rewards and tend to be disappointed if they do not get them. But these expectations have nothing to do with investments, and neither are they rooted in a conception of justice. (Blau, 1964, p. 195)     

Anticipation of future interaction and the bystander effect

Previous research suggests that people are slower to offer help in an emergency when there are other witnesses than when there are not. This finding has come to be known as the bystander effect. In research that has demonstrated this effect, however, the other witnesses were invariably anonymous others who had no relationship with the subject and with whom the subject probably did not expect to interact again. The present research examined the hypothesis that the expectation of participating in subsequent face-to-face interaction with other bystanders would cause the bystander effect to be minimized. Female college students were led to believe either that they would have no personal contact with the other participants in an ostensible group discussion, or that the participants would be involved in a later face-to-face discussion session. Each subject then participated in what she believed to be an anonymous discussion via intercoms, involving either one person or five persons beside herself. During this period, an ostensible co-subject experienced a choking fit. Help was offered more quickly among subjects who expected future interaction than among those who did not. In the no future interaction condition, latencies to help were longer in six-member than in two-member groups, but the comparable difference, although in the same direction, was not reliable among subjects who expected interaction. Presence of male “co-subjects” in an exploratory condition failed to inhibit helping. Discussion centers on the broader implications of the findings.     

Effects of altering outcome expectancies on pigeons' delayed conditional discrimination performance

An outcome-expectancy mediation theory of learning was tested in a series of transfer experiments with pigeons. The principal technique employed was a delayed two-choice conditional discrimination in which the subject's correct choice yielded a food reward on one kind of trial and a feedback tone on the other. According to the theory, this task engenders two-link mediational chains in that each conditional cue controls a particular outcome expectancy (S-E link) and the expectancy, in turn, cues a specific choice response (E-R link). Relative to the hypothetical mediators established by preceding training, transfer problems required either the same mediational chains, the alteration of one link in each chain, or the alteration of both links in both chains for optimal performance. The results of four separate transfer experiments confirmed detailed theoretical predictions, including that of an unusual nonmonotonic transfer effect. The relation of the present theory to earlier mediation theories is discussed.     

Gaze and emotional expression: The effects of message positivity-negativity and emotional intensity

The effects of emotional positivity-negativity and emotional intensity on actor's gaze were examined by simulating emotional situations to a camera. Female subjects were first asked to act out a neutral message as if they were speaking to a person to obtain a baseline for direct gaze. Subjects were then asked to perform a positive or a negative message to the camera. Half the subjects attempted to express the message with strong emotion; half expressed it with weak, ambivalent emotion. As expected, it was found that more direct gaze was maintained when expressing strong emotion. Whether the message was positive or negative did not affect gaze direction. The results were discussed in relation to the dimensions of nonverbal communication.     

Machiavellianism and spontaneous cheating in competition

Seventy-two undergraduates were assigned to groups defined by the combinations of the factors opportunity to cheat (yes, no), type of competition (personal, impersonal), and subject Machiavellianism (high, low). As predicted, cheating occurred in the opportunity to cheat, impersonal competition, high Mach group and in the opportunity to cheat, personal competition, low Mach group, extending the results of previous Machiavellianism research from situations in which cheating was explicitly encouraged by another person to a situation in which cheating was undertaken at the subject's own initiative.     

Assessment of social skills using a Thurstone Equal-Appearing Interval scale

Although Likert ratings of social skill are widely used in behavioral assessment, such ratings may have limited replicability potential and social validity. The present study compared the reliability of Likert and Thurstone Equal-Appearing Interval scales. The Thurstone-derived scale was slightly more reliable than its Likert counterpart. Moreover, the empirical and clinical potential of Thurstone scaling substantially exceeds that of Likert and other rating methods.     

A factor analytic and reliability study of the Devereux Child Behavior Rating Scale

The factor structure of the Devereux Child Behavior (DCB) Rating Scale was found to be different in the present study from those reported by the authors of the scale. Five of the 17 DCB factors were too unreliable to include in the present factor analysis. The findings of the present study were strikingly similar with other factor analytic studies of behavior rating scales in that only three main factors were found: Conduct Disorder, Personality Disorder, and Inadequacy-Immaturity.     

A simple stimulus cue for controlling disruptive classroom behavior

In two separate classrooms, a red light which had no specific consequences attached was used to reduce the talking-out and out-of-seat behavior of elementary school subjects. Following baseline phases, the light was introduced for a one-week period. An observer activated the light whenever the targeted behaviors occurred. Following a return to baseline, the light was reintroduced for a second one-week period. Results indicated that for both subjects a 95% or greater reduction in targeted behaviors occurred during the red-light phases. The results demonstrated the short-term effectiveness of a simple procedure which does not require specific back-up consequences for the reduction of disruptive behavior. The author concluded that studies using stimulus cues as part of reward or punishment procedures should employ a baseline procedure which controls for the effect of the stimulus cue without specific back-up consequences.This work was supported by Grant No. MH-18966 from the National Institute of Mental Health to Roberta Ray, Oregon Research Institute.
