Comparison of self-reports, reports by knowledgeable informants, and behavioral observation data

The strengths and weaknesses for the assessment of personality characteristics of self-reports, reports by knowledgeable informants, and measures based on behavioral observation data are discussed and compared It is suggested that measurement methods should be evaluated with respect to Loevinger's concept of structural validity The concept of structural validity is expanded to include evidence that the scores have properties paralleling the theoretical definition of the characteristic with respect to reliability over occasions, range of referent attributes sampled, and generality across situations or the specification of situation parameters Each of the methods is evaluated for its potential to construct measures with structural validity for different models of constructs The methods are also discussed in relation to several other common threats to validity, specifically, threats stemming from the respondent, from the investigator, and from sampling errors It is likely that demonstrations of convergence between these methods will be possible for some but not all constructs It is also suggested that the examination of structural validity will contribute to the evolution and refinement of constructs appropriate for interactionist theories     

Perceptual changes in taste mixtures

Three studies were conducted to quantify perceptual changes that occur when sapid chemicals are tasted in mixture solutions. The primary effect when mixing sweetness (glucose or fructose) with salt (NaCl), sour (citric acid), or bitter (quinine sulfate) was to reduce the intensity of each taste in the mixture. The reduction was not equal for the two components, although the overall (total) taste intensity of the mixture appeared to be approximately 50% of the sum of the intensities of the unmixed components. Mixtures of sweet and salt developed an “unblended” or “clashing” taste, in which the components alternated in attempting to dominate the taste percept. Sweet mixed with either sour or bitter blended in almost all proportions. The “flavor” of sweetness in mixtures differed from that of simple sugar sweetness, suggesting that the presence of a second taste modified the qualitative aspect of sweetness. The magnitude of change in sweetness quality depended upon the sugar being rated, and upon the quality and intensity of the second, or modifying, taste.     

Corners,receptive fields,and visually evoked cortical potentials

Alternating stimuli with herringbone patterns were used to obtain visually evoked cortical potentials (VECPs) from three human Ss. Two sets of stimulus patterns were used, one with sharp corners and one with the corners rounded off. Each set ranged in angularity from 180 to 45 deg in 45-deg steps. Results showed that: (a)VECP response amplitude was greatest for the 90-deg-corner pattern, (b) response amplitude was greater for the 45-deg-corner pattern than for the 135-deg-corner pattern, and (c) cornered and rounded patterns evoked responses of greater amplitude than those evoked by the straight (180-deg) patterns. Also, the peak latency of responses to cornered patterns was shorter than that of responses to rounded and straight patterns.     

Construct validation of the dependency and self-criticism scales of the depressive experiences questionnaire

S. J. Blatt (Psychoanalytic Study of the Child, 1974, 29, 107–157) distinguished between two types of depressive experiences, one characterized by strong dependency needs and the other by self-criticism and guilt. This paper reports a series of validation studies of the Depressive Experiences Questionnaire (DEQ), which was developed to measure individuals' vulnerabilities to these types of experiences (S. J. Blatt, J. P. D'Afflitti, & D. M. Quinlan, Journal of Abnormal Psychology, 1976, 85, 383–389). The Dependency and Self-Criticism scales were shown to be stable in the face of both a 13-week interval and the receipt of midterm grades. Dependency was associated with conflict concerning the expression of hostility and, in males, feelings of helplessness. Self-Criticism was associated with low self-esteem and high levels of morality-conscience guilt. In a study of behavior in dyadic problem-solving tasks, Dependency in males was found to be negatively related to task leadership, and Self-Criticism in females tended to be negatively related to judged likeability. On the other hand, little support was found for the hypotheses that Dependency would be related to field dependent cognitive style and to the use of primitive defense mechanisms. The results were viewed as supporting the utility of Blatt's distinction between the two types of depression, but a number of anomalous findings indicated a need for further study of the DEQ. The question of the developmental level of the two types of depression, possible sex differences in the correlates of the scales, and the possibility of situational specificity in individuals' responses were identified as the areas most in need of study.     

Spontaneous trait inferences as self-generated primes: implications for conscious social judgment.

The priming literature has documented the influence of trait terms held outside of conscious awareness on later judgment relevant to the primed trait dimension. The present research demonstrated that spontaneous trait inferences can serve as self-generated primes. In Experiment 1, Ss instructed to memorize trait-implying sentences (thus spontaneously inferring traits outside of consciousness) showed assimilation effects in judgment. Ss instructed to form inferences from these sentences (thus consciously inferring traits) showed contrast effects. Experiment 2 demonstrated that these findings were due to semantic activation rather than to a general evaluative response. When evaluatively inconsistent trait constructs were primed, similar patterns of assimilation and contrast were found. Implications for the ubiquitous occurrence of priming through the process of social categorization are discussed.     

Person organization with a memory set: are spontaneous trait inferences personality characterizations or behaviour labels?

Recent research on impression formation has demonstrated that perceivers can categorize the action of target actors in terms of the traits that those behaviours represent, and that they do so in a spontaneous fashion, with neither the intent of categorizing nor the awareness of categorizing. This has resulted in a discussion about what these inferences refer to. Are they simple summaries of the behaviour without implications for the personalities of the people enacting those behaviours, or are they inferences about the target's disposition? The current experiment uses a procedure from the person memory literature to establish that these inferences are in fact references to the qualities of the target actors. Set size effects demonstrate that perceivers are organizing their inferred traits in person nodes; the person serves as the superordinate cue to which inferences are attached. This not only provides evidence that inferences formed spontaneously refer to the personality characteristics of the target, but also provides the first evidence of person organization under simple instructions to memorize stimulus information. The implications of the richness of the target information for spontaneously forming person inferences and for person organization in general are discussed.
