Deviation from hierarchical structure in recall: Is there an “optimal” structure?

Past research has suggested that proportionally more superordinate than sub-ordinate propositions are recalled from expository texts, following a hierarchical analysis of the text structure. Since free recall has typically followed this hierarchical pattern, several researchers have assumed that the related memory structures are isomorphic to the text structure. However, few of these studies have examined how individual differences and text structure interact to affect free recall. In two experiments, the assumption of hierarchical patterns of children's recall of expository text was tested. In Experiment 1, high- and average-ability fourth graders (9 years old) were asked to read and recall a passage. Experiment 2 was a replication and extension of Experiment 1. In this experiment, fourth and sixth graders (9 and 11 years old) read and recalled a different passage. The combined results of both experiments support the notion that there is probably no one optimal hierarchical structure for storage and retrieval of expository text.     

Structural models for the mediation of salience effects on attribution

Previous research has demonstrated that salient information is overrepresented in causal attributions. Two experiments were conducted to investigate potential mediators for this effect and to make a case for the use of structural models in explanations of process. Two mediators were considered: enhanced visual recall of salient stimuli and exaggerated schema-relevant recall of salient stimuli. Although analyses of variance supported the visual recall model, structural analyses demonstrated its implausibility. Analyses of variance and structural models revealed that schema-relevant recall, that is, information seen as representative of causal influence, is a plausible mediator; this was particularly true of relevant visual information. Results suggest that salience effects (S. E. Taylor & S. T. Fiske in L. Berkowitz (Ed.), Advances in experimental social psychology (Vol. 11). New York: Academic Press, 1978) are due to: (a) the attentional advantage of inherently salient visual events and (b) the influence of stored visual and nonvisual schema-relevant information on causal judgments.     

The self-serving attributional bias: Beyond self-presentation

An experiment was conducted to provide empirical support for the notion that asymmetrical causal attributions for favorable and unfavorable outcomes result from a self-serving attributional bias that occurs independently of self-presentational concerns. Subjects did either well or poorly on an ego-involving test for which their performance, attributions, and evaluations of the test were either public or private. A pattern of self-serving responses for subjects' attributions and evaluations of the test was found in the private conditions, thus providing evidence of the influence of outcome favorability on individuals' perceptions of causality. Theoretical and practical implications of these finding are discussed and suggestions for future research are offered.     

On comprehending idioms: Do children get the picture?

This study examines children's comprehension of idioms. First, third, and fifth grade children (6, 8, and 10 years old) and college adults were read short stories containing contextual information and a key terminal sentence. The contextual information biased either an idiomatic, a literal, or am ambiguous (neutral) interpretation of the terminal sentence. The terminal sentence contained either an idiom (“fix his wagon”) or a changed form (“repair his wagon”) of the idiom. These manipulations were used to determine the role of contextual information and the conventional forms of idioms in idiom comprehension. After each story, the subjects were asked to explain the terminal sentence and to answer a “yes-no” question about the action described in the story. The results showed that idiomatic explanations and interpretations occurred more frequently for the idiom than the changed forms, and that there were strong developmental increases in making idiomatic interpretations of both forms. The results are discussed in terms of two current models of idiom comprehension.     

The use of structured learning therapy and transfer programming with disruptive adolescents in a school setting

In behavior change literature, little attention has been paid to the systematic study of variables affecting transfer of training. The present study employed a skill-training method known as Structured Learning Therapy (SLT) for the dual purpose of testing the effectiveness of this method and to identify variables that will promote transfer of training. Forty-three disruptive male adolescents were assigned to three experimental and two control conditions. One experimental group received SLT plus an additional transfer-enhancing procedure referred to as Transfer Programming (TP) which consisted of in vivo practice of treatment gains and peer reinforcement. Another group received only SLT, and a third group received only TP. One control group received only brief instructions pertaining to the nature of the skill, while the second group served as an attention control. Consistent with predictions, the results were that the two groups receiving the SLT performed significantly better than the three groups not receiving SLT on all dependent measures at posttest. These differences generally maintained at follow-up. Contrary to expectations, the implementation of TP did not prove to promote transfer of training beyond that found with SLT alone.     

Counting eliminates the repetition effect in judgments of temporal duration.

College student subjects estimated the duration of time intervals (8–54 sec) by counting or not (N=35 per group). Counting eliminated the repetition effect (a decline in the magnitude of estimations across trials), and resulted in a truncation of the psychophysical function. The former result was interpreted as contrary to Treisman's (1963) model. The latter result was attributed to the effortfulness of counting, which was established in a subsequent experiment.     

Autonomic responsivity of subjects with body boundary differences during white noise stimulation

A white noise stimulus (85 dB) was used to investigate differences in heart rate (HR) and skin conductance (SC) responsivity of 32 male subjects. The subjects were divided into high and low body boundary (HB and LB) groups, according to Fisher's (1970) revised scoring system of Holtzman Inkblot responses. The hypothesis predicting a significantly larger HR response, that is resistant to habituation, for the LB group, was confirmed. The prediction that the HB group would reveal a larger SC amplitude response accompanied by a shorter recovery time, was supported for the latter. The results confirmed the hypothesis, based on behavioral observations, that the HB individual experiences stress less intensely than the LB person. It also points to individual differences as an important variable in evaluating noise as a stressor.     

Adaptation of the category boundary between speech and nonspeech: A case against feature detectors

Two experiments were performed employing acoustic continua which change from speech to nonspeech. The members of one continuum, synthesized on the Pattern Playback, varied in the bandwidths of the first three formants in equal steps of change, from the vowel /α/ to a nonspeech buzz. The other continuum, achieved through digital synthesis, varied in the bandwidths of the first five formants, from the vowel /æ/ to a buzz. Identification and discrimination tests were carried out to establish that these continua were perceived categorically. Perceptual adaptation of these continua revealed shifts in the category boundaries comparable to those previously reported for speech sounds. The results were interpreted as suggesting that neither phonetic nor auditory feature detectors are responsible for perceptual adaptation of speech sounds, and that feature detector accounts of speech perception should therefore be reconsidered.     

Semantic focus and sentence comprehension.

Reaction time to detect a phoneme target in a sentence was found to be faster when the word in which the target occurred formed part of the semantic focus of the sentence. Focus was determined by asking a question before the sentence; that part of the sentence which comprised the answer to the sentence was assumed to be focussed. This procedure made it possible to vary position of focus within the sentence while holding all acoustic aspects of the sentence itself constant. It is argued that sentence understanding is facilitated by rapid identification of focussed information. Since focussed words are usually accented, it is further argued that the active search for accented words demonstrated in previous research should be interpreted as a search for semantic focus.
