Relation of the verbal transformation and the phonemic restoration effects

This study examined the relationship between illusory changes of repeated words (“verbal transformations” or VTs) and illusory presence of phonemes replaced by noise (“phonemic restorations” or PhRs). Separate groups of 20 subjects were each presented with one of four taped variations of the repeated stimulus word “magistrate”: stimulus intact (MAGISTRATE); speech sound “s” removed and replaced with a silent gap (MAGI TRATE); speech sound “s” removed and replaced with a louder extraneous sound (MAGI¹TRATE); syllable “gis” removed and replaced with a louder extraneous sound (MA⁷¹TRATE). The stimuli MAGI¹TRATE and MA⁷¹TRATE evoked PhRs, and with these stimuli, the phonetic changes corresponding to VTs were concentrated at the perceptually restored portions of the word. It is suggested that both PhRs and VTs are related directly to perceptual processes employed normally for the correction of errors and resolution of ambiguities in speech. Other effects of PhRs upon VTs are described and implications of these findings for mechanisms underlying speech perception are discussed.     

Bizarreness effects in verbal tasks and subject-performed tasks

Abstract

Recognition and cued recall of ordinary action phrases (e.g. “open the book”) and bizarre ones (e.g. “plant the hammer”) were compared under two encoding conditions: in verbal tasks (VTs), subjects learned the phrases by simply listening to them; in subject-performed tasks (SPTs), subjects learned the phrases by performing the denoted actions (without real objects). Memory performance was better after SPTs than after VTs in recognition and cued recall. In addition to this already established finding, it was observed that recognition was better for bizarre phrases than for ordinary ones after VTs and that bizarreness was unrelated to recognition after SPTs. Cued recall, on the other hand, depended on bizarreness after VTs as well as after SPTs and, in contrast to the recognition findings, ordinary phrases were recalled better than bizarre phrases. This pattern of findings was explained by the assumptions that lexical and conceptual information is encoded after VTs and motor information is additionally encoded after SPTs, and that different kinds of information are used in recognition and cued recall, and after VTs and SPTs.     

The role of movement and object in action memory: a comparative study between blind, blindfolded and sighted subjects

Two experiments systematically compared four SPT conditions involving real/imaginary movement and real/imaginary object with one VT condition involving no enactment and no object. To test the effect of visual information on SPT memory, sighted subjects were compared with blindfolded subjects (in Experiment 1) and blind subjects (in Experiment 2). All subjects learned all SPTs and VTs. Free recall data showed no difference between the SPT conditions and between the groups of subjects; only blind subjects were found to be limited in the use of visualization strategy. All SPTs were recalled better than VTs, indicating that the enactment effect is not determined by either movement or object alone, rather both have an effective role and are equally involved for obtaining the enactment effect. The results provide no support for the motor encoding and multimodality views of SPTs, but are in line with the episodic integration view which assumes that neither movement nor object are of special importance, rather both have contribution in the enactment effect.     

Differential relational encoding of categorical information in memory for action events

Memory for action phrases is better if the actions are enacted in subject-performed tasks (SPTs) than if they are only listened to in verbal tasks (VTs). This effect is ascribed to better item-specific encoding of SPTs than of VTs. The role of interitem relational information is controversial, and the findings of clustering with categorically structured lists are inconsistent (see Engelkamp, 1998). The present study contributes to clarifying these effects by demonstrating that intentional relational encoding can be used more efficiently in VTs than in SPTs and influences the degree of clustering. If the list structure is not obvious, inducing intentional encoding by presenting the category labels prior to list presentation and asking subjects to use this preinformation increases clustering in VTs but not in SPTs. Without preinformation, clustering scores of VTs and SPTs did not differ, with preinformation, clustering of VTs was stronger than that of SPTs. The authors suggest how the inconsistent findings with regard to clustering effects can be explained.     

Organisation and Recall in Verbal Tasks and in Subject-performed Tasks

In memory for subject-performed tasks (SPTs), subjects encode a list of simple action phrases (e.g. "lift the pen", "open the book") by performing these actions during learning. Performing tasks has proved to be a much more efficient type of encoding than verbal tasks (VTs), in which subjects only listen to the action phrases in order to memorise them. It is assumed that good item-specific encoding after SPTs plays an important role in the SPT effect. The role of relational encoding for the SPT effect is less clear, as is the question of whether SPT encoding is automatic or controlled. Two experiments were conducted to address these issues. Subjects learned lists which were categorically structured in VTs and SPTs, under focal attention or divided attention. The results indicated that relational encoding does not differ between VTs and SPTs, and that free recall is impaired in both cases by divided attention, more so in VTs than in SPTs. It is concluded that the SPT effect is primarily based on item-specific information rather than on relational information, and that VTs are more dependent than SPTs on active encoding.     

Behavioral treatment of obsessive-compulsive neurosis

Three chronic and severe obsessive-compulsive neurotics were treated with behavioral intervention strategies and psychotropic medication. The effects of treatment were evaluated in three separate experiments with single case experimental designs. The results suggest that response prevention was effective in reducing ritualistic behavior while the effects of flooding and antidepressant medication added little to outcome. The results also suggest that strategies aimed only at reducing compulsive behavior per se are insufficient in eliminating other associated difficulties (e.g., depressive symptoms, interpersonal problems) and that a comprehensive approach to treatment is needed.     

Biasing evaluations to appear unbiased: A self-presentational paradox

Subjects interviewed a confederate posing as a job applicant. In a 2 × 2 factorial design, half the subjects were insulted by the confederate at the end of the interview and half were not insulted. Half the subjects were observed by the experimenter during the final phase of the interview and evaluated the confederate publicly. The remaining subjects were unobserved during the interview and evaluated the confederate anonymously. As predicted, subjects who were publicly insulted were more favorable toward the confederate than were subjects who were privately insulted. Within the public/insult condition, subjects scoring high on Snyder's (1974, Journal of Personality and Social Psychology, 30, 526–537) self-monitoring scale were more favorable toward the confederate than were subjects scoring low on this scale. The positivity bias occurred only on highly subjective ratings, which are most prone to the appearance of bias. The results are discussed in terms of the subjects' desire to avoid the appearance of bias by biasing their evaluations.     

Individual differences in self-reinforcement style and performance in self-and therapist-controlled weight reduction programs

Thirty-seven overweight subjects were recruited from the staff of a V. A. Hospital for a weight reduction program. A self-reinforcement (SR) test was administered prior to treatment and subjects were classified as high or low self-reinforcers. Subjects were then exposed to one of two behavioral weight-reduction programs or a minimal treatment control condition. One treatment program emphasized self-control (SC) and the other incorporated a therapist controlled financial contingency for weight loss (EC). A significant interaction was found between SR group and treatment condition. High SR subjects lost weight at the rate of 1.49 pounds per week in the SC condition and only 0.37 pounds per week in EC. Low SR subjects lost at the rate of 1.06 and 1.01 pounds per week respectively in SC and EC. Implications for treatment and future research were discussed. The financial contingency had either neutral or negative effects. Caution was advised for any future use of that procedure.     

Post-iconic visual storage: chunking in the reproduction of briefly displayed visual patterns

Two experiments are reported which investigate the organization of visuospatial information in post-iconic storage. In both experiments, stimuli consisting of 10 disks randomly placed in a four-by-five array were tachistoscopically presented to subjects whose task was to recreate the pattern. In Experiment 2, reproduction was constrained (on a row-by-row basis) while in Experiment 1 it was unconstrained. The results of Experiment 1 showed that subjects recalled in terms of “chunks” of spatially adjacent disks, with most “chunks” consisting of about three of four disks. Within each sequence of 10 responses the probability of correctly recalling a chunk decreased with its serial position but was relatively independent of chunk size per se (for chunks containing seven or less disks). In addition, clear topographical variations in accuracy were found, which tended to covary strongly with order of recall. In Experiment 2, the order of reproduction was prespecified (either top row down to bottom row, or bottom row up to top row) in order to induce chunking by rows. The direction of reproduction was either pre- or post-cued. The results of this study showed that subjects encode the stimulus, wherever possible, in a form which is compatible with the constraints imposed on recall order. The results for the postcued conditions provide strong support for the argument that topographical variations in accuracy are a function of variations in accuracy of encoding, and not simply a function of order of report. The results are discussed in terms of an attentional model. It is proposed that a general “anticipatory schema” (cf. Neisser, Cognition and Reality 1976) presets the distribution of attention in the visual field, preselects a set of coding heuristics, and subsequently interacts with the present stimulus pattern. Spatial discontinuities in the distribution of attention resulting from this interaction are regarded as “defining” chunks of stimulus elements.     

Memory for actions: Item and relational information in categorized lists

Enacting action phrases in subject-performed tasks (SPTs) leads to better free recall than hearing or reading the same materials in verbal tasks (VTs). This enactment effect is usually explained by better item-specific information in SPTs than in VTs. The role of relational information is controversial. In the present paper, we will take the multiple recall approach to study the role of item and relational information in memory for actions by computing the number of item gains and the number of item losses over trials. This approach has previously been applied to lists of unrelated action phrases. We applied it to categorically related lists, also allowing a measure of relational information by clustering scores. It was found that SPTs produced more item gains than VTs. This finding confirmed the assumption that SPTs provide better item-specific information than VTs. The number of item losses did not differ between VTs and SPTs. This finding suggests that relational information is equally provided by VTs and SPTs. However, the organizational scores showed a more differentiated picture. Clustering was greater in SPTs than in VTs with randomly presented lists, but not with blocked lists. We suggested that these results, as well as other findings from the literature, could be explained by distinguishing automatic and strategic processes and the types of item associations that are addressed by these processes.     

Lateralization of temporal lobe dysfunction and verbal encoding

The contribution of encoding deficits to verbal-learning difficulties known to be associated with temporal lobe dysfunction was investigated. Auditory and visual false-recognition tasks, which assess verbal encoding strategies, were given to patients with left-temporal-lobe (LTL) and right-temporal-lobe (RTL) surgical excisions and to a group of normal controls (NC). On both auditory and visual tasks, LTL patients made significantly more false-recognition errors than the other subjects on related, but not unrelated, words in the test list. The findings indicate that LTL patients are able to initially encode verbal material and that a breakdown in information processing occurs at a later stage. On the auditory tasks, the performance of RTL patients did not differ from that of NC subjects. However, on the visual tasks, RTL patients, as compared to both LTL and NC subjects, made fewer false-recognition errors. The performance of RTL patients, in contrast to LTL patients, could be interpreted as a reduced encoding of the visual attribute of verbal material. Another possible explanation considered was difficulty in familiarity discrimination.     

A new look at selective exposure

The relevance of the personality dimension “repression-sensitization” (D. Byrne in B. A. Maher (Ed.), Progress in experimental personality research, Vol. 1, NY: Academic Press, 1964, pp. 169–219) to selective exposure processes was investigated. Experimental repressors (who typically employ “avoidance” strategies in dealing with threatening stimuli) and experimental sensitizers (who generally “approach” threatening stimuli) were allowed to choose and keep one of two pairs of painting reproductions, each pair containing one positively and one negatively valued painting. After the decision, which experimental subjects believed terminated the experiment, subjects were allowed to inspect the alternatives ad libitum for 75 sec. Eye gaze during this period was unobtrusively videotaped. Compared to their matched controls, who were simply asked to inspect the paintings in order to decide which ones they liked best, experimental repressors inspected paintings that were consonant with their choices and avoided looking at paintings that were dissonant with their decisions. Experimental sensitizers did not manifest such postdecisional selective exposure. The implications of these results for past and future research on dissonance-produced selective exposure were discussed.     

Assertive training versus rehearsal and the importance of making an assertive response

This study dealt with whether mere practice would enhance assertion, and whether assertive training would reduce negative effect in simulated target situations, even when subjects (Ss) made no overt response. Males reporting difficulty with authority figures received either rehearsal alone or the complete assertive training package; in a subsequent behavioral test half in each group were told to make a response, with the remainder instructed to remain silent. Objective ratings revealed marked improvement following assertive training, while the effects of practice alone were negligible. For Ss receiving assertive training, reduction in selfreported negative affect in the target situations appeared to be independent of whether or not they engaged in overt verbalization, suggesting that assertive training, per se may enhance feelings of well-being.     

A within-subjects analysis of the relationship between memory span and processing rate in short-term memory

A within-subjects analysis of the relationship between memory span and processing rate for four stimulus classes in short-term memory indicated that while the two factors are correlated when averaged data is considered, as shown by Cavanagh (Psychological Review, 1972, 79, 525–530), the strength of the relationship for individual subjects varies from zero to unity. The intersubject correlations for each stimulus class were not consistent with the view that a unified model may be advanced to account for performance in recall and recognition tasks in shortterm memory.     

Individual differences in electrodermal activity as a function of subjects' anxiety

The present study examines the relationships between electrodermal activity (EDA) and anxiety in an attention demanding task, by looking at the neuropsychology of individual differences. 261 normal volunteer female students completed the Cattell anxiety form, and only subjects with extreme anxiety scores (deciles 0, 1 and 2 on the one hand, N = 22; deciles 9 and 10 on the other hand, N = 24) were retained. Subjects were presented a set of 16 stimuli (8 neutral and 8 emotional slides) in a randomized order (different for each subject), of 35 msec and 1 sec duration and a randomized inter-stimuli time of average 45 sec. Skin conductance levels (SCLs), interstimuli spontaneous fluctuations (SSCRs), skin conductance response (SCR) amplitudes and electrodermal latencies were recorded, as well as skin temperature (ST). Highly anxious subjects showed significantly lower SCLs, lower SCR amplitudes, fewer interstimuli SSCRs and longer latencies than subjects with low anxiety, whereas ST did not differ between groups. These results, showing that in normal subjects there are individual electrodermal differences as a function of trait-anxiety scores, are discussed both in terms of individual differences in self-regulatory neural processes and in reference to Gray's anxiety theory.     

Focus of attention and placebo utility

The effects of focus of attention and expected drug effects on reactions to a placebo were examined in two experiments. In the first experiment self-aware and non-self-aware subjects were given a placebo that was said to be either performance-facilitating or inhibiting and then they worked on a set of arithmetic problems. It was expected that the non-self-aware subjects, but not the self-aware subjects, would display a self-serving bias in their attributions regarding the effects of the placebo. Specifically, it was predicted that non-self-aware subjects would attribute more arousal to the performance-inhibiting drug than the performance-facilitating drug since such attributions would be more psychologically beneficial or “useful” in the sense that they would make actual performance on the task look more impressive. Consistent with these predictions, there was evidence of a self-serving bias in drug reactions only among the non-self-focused subjects. Those who were made self-aware did not respond differentially to the two types of drug information. Instead, they appeared to respond in line with their actual (aroused) internal states by attributing some arousal to both drugs. In the second experiment arousal was reduced by eliminating the task, and this time self-focused subjects again appeared to be more aware of their actual internal states, as they reported less reaction to the placebo, regardless of the effects ascribed to it. Two conclusions are drawn from these results: (a) perceived drug utility does effect placebo responsiveness, and (b) self-focused attention increases awareness of internal states, but not necessarily the causes of those states.     

SPT效应的自动突显机制:来自输出监测的证据

研究采用"对回忆的再认"范式,从输出监测的角度考察了操作效应的提取机制。实验1结果显示,被试操作任务条件下的自由回忆的系列位置成绩缺乏首因效应,却拥有扩展的近因效应;被试操作任务条件下的"对回忆的再认"成绩显著差于语词任务下的成绩,差异具体表现在组块2~9、10、11和12上,表明在上述组块,被试操作任务条件下的提取存在自动突显,即操作效应得益于这些组块在提取时的自动突显。实验2结果显示,在类别测验下,被试操作任务和语词任务的自由回忆成绩拥有相似的系列位置曲线,而"对回忆的再认"结果同实验1。研究认为自由回忆的系列位置效应与自动突显机制之间不存在直接的因果关系,而"对回忆的再认"范式则能敏感地测量出操作效应的提取机制。     

Misattribution of arousal and attraction: Effects of salience of explanations for arousal

Based on previous research demonstrating that salience of a plausible cause increases the likelihood of causal attribution (S. E. Taylor & S. T. Fiske, in J. Berkowitz (Ed.), Advances in Experimental Social Psychology (Vol. 11), New York: Academic Press, 1978) it was predicted that salience of plausible causes of arousal would affect romantic attraction. Male subjects were differentially aroused by running in place. Aroused subjects were particularly likely to be attracted to an attractive female confederate if they expected to meet her (high salience of confederate) and if cues associated with the running in place were minimized (low salience of exercise). Though results are consistent with a misatribution of arousal hypothesis, it is suggested that emotion schemata are a potentially more useful explanation.     

Male versus female Siamese fighting fish as reinforcing stimuli for conspecific males in single- and two-choice operant situations

Two experiments attempted to determine the reinforcing effectiveness of visual exposure to a female versus a male stimulus in male Siamese fighting fish (Betta splendens). This was accomplished by making male or female presentation contingent upon an operant ring swimming response in single- (Experiment 1) and two-choice (Experiment 2) continuous reinforcement operant situations for 1 hr per day. It was found that visual exposure to a female stimulus was behaviorally reinforcing in a way comparable to that typically found in intermale studies. If given a choice, male test subjects were observed to demonstrate a consistent preference for the female as opposed to the male stimulus. The results are discussed in terms of stimulus discrimination and approach-avoidance conflict as differentially elicited by male and female target stimuli.
