Causal judgments about relations between multilevel variables

Three experiments presented stimulus information about cause and effect variables taking 3 quantitative values. Judgments tended to vary in accordance with considerations of conditions affecting the validity of causal inference from correlational data: whether causal candidates were presented simultaneously or in a temporal order such that one could affect the other and whether candidates were confounded with each other. The results supported a general hypothesis that causal judgments are moderated in accordance with acquired methodological intuitions. The fourth experiment showed that tendencies in correlation judgment were different from those in causal judgment, further supporting the hypothesis that causal judgment from multilevel variable information is, to some extent, determined by processes or conceptual frameworks specific to the domain of causal cognition.     

Linear relations amongk sets of variables

A family of solutions for linear relations amongk sets of variables is proposed. It is shown how these solutions apply fork=2, and how they can be generalized from there tok3.The family of solutions depends on three independent choices: (i) to what extent a solution may be influenced by differences in variances of components within each set; (ii) to what extent the sets may be differentially weighted with respect to their contribution to the solution—including orthogonality constraints; (iii) whether or not individual sets of variables may be replaced by an orthogonal and unit normalized basis.Solutions are compared with respect to their optimality properties. For each solution the appropriate stationary equations are given. For one example it is shown how the determinantal equation of the stationary equations can be interpreted.     

Electrophysiological analysis of stimulus variables in equivalence relations

Recently, electrophysiological measures have been used to evaluate the functional overlap between semantic relations and laboratory-defined equivalence relations with abstract stimuli. Several studies using semantic judgment procedures have shown that accompanying EEG-measured neural activity for stimulus pairs from equivalence classes is very similar to that of word pairs from participants' native language. However, those studies often included pronounceable elements (e.g., written nonsense syllables) as at least one member of the experimentally defined classes. The present study conducted EEG studies that contrasted classes with and without such elements. Two groups of undergraduate students completed a matching-to-sample procedure to establish 3 4-member equivalence classes. For Group 1, samples and comparisons were pronounceable pseudowords and abstract figures. For Group 2, the matching-to-sample stimuli were abstract figures only. EEG data recorded during the semantic judgment tasks showed waveform patterns compatible with prior studies of semantic relations in Group 1 but not in Group 2.     

Suppressor effects in the relations of psychological variables to resting blood pressure

The role of suppressor effects in obscuring the relation of psychological variables and blood pressure was studied. Forty-five nonmedicated patients in a family practice rated themselves relative to their peers on a series of characteristics. Two of these, trapped and lonely, exhibited marked suppressor effects in their relationship with each other and resting blood pressure. Self-ratings of lonely exhibited a moderately strong positive association with ratings of trapped (r = .63) while only ratings of lonely showed a significant correlation with resting systolic blood pressure (r = .31). Yet when the suppressor effects of the ratings on feeling lonely were removed in the regression analyses, the ratings on feeling trapped showed a significant positive association with resting systolic pressure (r = .42). Similarly, while neither ratings on feeling lonely or on feeling trapped showed separately a significant association with resting diastolic pressure, when suppressor effects were removed in the regression analyses, the ratings of trapped were significantly associated with diastolic pressure in a positive direction (r = .34) and ratings of lonely were significantly associated in a negative direction (r = .33). The significance of this specific suppressor effect and the implications of suppression for psychosomatic research are discussed.     

Bulimia and object relations: MMPI and Rorschach variables

Rorschach and Minnesota Multiphasic Personality Inventory (MMPI) responses from persons vomiting to manage body weight and fat phobia were compared to those from a matched control group to determine the levels of personality structure. These responses were also contrasted with those of representative groups from normal and personality disordered populations. Findings were that the bulimic group's test protocols differed significantly from those of the control group, displaying evidence of serious cognitive slippage and dramatic, emotional and erratic personality structures arrested at the differentiation subphase of ego development. The clinical importance of timely developmental diagnosis and interventions designed to promote object constancy was discussed in light of these findings.     

The deviant citizen: Measuring potential positive relations between counterproductive work behaviour and organizational citizenship behaviour

Studies have shown a strong negative correlation between counterproductive work behaviour (CWB) and organizational citizenship behaviour (OCB), and opposite correlations with hypothesized antecedents. Such observed correlations may have been erroneously caused by three measurement artefacts: items measuring absence of CWBs, rather than behaviours that exceed requirements or expectations in OCB scales; supervisory halo; and agreement rather than frequency response format. A new OCB scale, the OCB‐checklist (OCB‐C) was used that did not have these artefacts. Contrary to prior expectations from the literature, positive relations were found between CWB and OCB, and stressors and OCB. Theoretical explanations for positive CWB/OCB relations (demand‐elicited OCB, social loafing, work process problems, rater perceptions and attributions, and aggravated job stress processes) are discussed.     

Concurrent and prospective relations between attention to emotion and affect intensity: an experience sampling study

Theorists contend that emotional awareness is vital to being able to use emotional information adaptively. The extent to which individuals attend to and value their feelings, or attention to emotion, is a facet of emotional awareness. Little research, however, has examined whether attention to emotion affects the magnitude or intensity of emotional experiences. In the present study we examined the relations between attention to emotion and levels of affect in 53 healthy adults. Participants carried hand-held electronic devices for approximately 7 days and were randomly prompted eight times per day to answer a series of questions. At each prompt, participants reported attention to emotion, current negative affect (NA), and positive affect (PA). All findings presented were computed using multilevel modeling. Replicating findings obtained using trait-level measures, we found that attention to emotion was associated concurrently with higher levels of both NA and PA. We also found prospectively that attention to emotion at one prompt predicted a decrease in levels of NA, but no change in levels of PA, at the subsequent prompt. These findings suggest that emotional processes serve different functions over time and highlight the role of attention to emotion in affect regulation.

Exploring the relations between traits and emotions

The relationships among traits and among emotions have been well researched and are well known, but few experimental probes of the relationships between traits and emotions have been undertaken. The present investigation sought to describe the relations that exist between traits and emotions. The Comrey Personality Scale (a trait inventory) and the Profile of Mood States (an emotion inventory) were administered to 140 students and the subscales were correlated using canonical procedures. The resulting canonical correlations may be specified in bipolar summary form as follows: Neurotic-Stable was found to be correlated with Depressed-Hopeful; Introverted-Extraverted was found to be correlated with Quiescent-Vigorous; and Empathic-Egocentrical was found to be correlated with Content-Confused. Furthermore, the predictive strength between the trait set and the emotion set was reasonably good, although substantially better when traits rather than emotions served as the predictors.     

Measuring psychophysiologic variables during conversations. Quantifying pulse volume changes

Little is known about connections between events in verbal communication and related physiological variables. Usually used procedures in quantification of pulsevolume data are based on simplifications neglecting essential characteristics of the curve between heart beats. It is shown that the concept of interbeat-intervals (IBI) underlying conventional methods hides these characteristics putting up with a delay in time between heart beats and related verbal factors. An alternative procedure of the extraction of period and amplitude is demonstrated. A software-package is developed to transform and interactively control the analysis of the pulsevolumesignal (filtering and vector-transformation). As results quasi-continuous time series of period and amplitude of the pulsecurve are shown, tracing the shape of the curve in each cardiac cycle. Some first applications of the method in stress research are discussed. The method is appropriate especially for detecting "short time" changes of cardiac activity in naturalistic observational settings (e.g. dyadic interaction).     

Perceived causal relations: novel methodology for assessing client attributions about causal associations between variables including symptoms and functional impairment

Researchers have argued that the investigation of causal interrelationships between symptoms may help explain the high comorbidity rate between certain psychiatric disorders. Clients' own attributions concerning the causal interrelationships linking the co-occurrence of their symptoms represent data that may inform their clinical case conceptualization, treatment, and psychological theory regarding the etiology of comorbid disorders. The present study developed and evaluated a novel psychological assessment methodology for measuring Perceived Causal Relations (PCR) and examined its psychometric properties as applied to the question of whether posttraumatic stress and anxiety symptoms represent causal risk factors for depressive symptoms in 225 undergraduates. Participants attributed their symptoms of anxiety and posttraumatic reexperiencing as significant causes of their depressive symptoms. Exploratory analyses identified a listing of symptoms reliably attributed as significant causes of other symptoms and functional impairment, as well as a listing of symptoms reliably attributed as significant effects (outcomes) of other symptoms and functional impairment. The PCR method has promise as an idiographic approach to assessing the causes and consequences of comorbid psychiatric symptoms and associated functional impairment. Research is required to assess the relevance and replicate these findings in distinct psychiatric groups experiencing various symptomatic presentations. Future research may also examine PCR ratings associating other individual differences, for example, between measures of history (e.g., life events), life choices, and personality.     

The missing link in the relations between intelligence and personality

This study investigated the relationships between performance on tasks representing five cognitive domains (quantitative, categorical, spatial, causal, and propositional reasoning), self-attribution of ability in regard to them and also in regard to three general cognitive functions (processing speed, working memory, and self-monitoring and self-regulation), and the Big Five factors of personality (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience). The participants (n=629) were about equally drawn from each of the age years 12–17. Structural equation modeling analyses were conducted to examine the construct validity of scores on the three research instruments. Moreover, structural equations modeling showed that self-attribution of ability is, to some extent, dependent on cognitive performance. Cognitive performance is weakly related only to two of the Big Five (openness and conscientiousness). Self-attribution of ability is substantially related to all but the neuroticism factor. Apart from openness to experience, the dependence of personality dimensions on the dimensions of cognitive self-representation tends to weaken with age. It is concluded that the influence of cognitive abilities on personality is mediated by self-awareness about them and implications are discussed.     

On the relations between crowding and visual masking

To study the question of which processes contribute to crowding and whether these are comparable to those of visual temporal masking, we varied the stimulus onset asynchrony (SOA) between target and flankers in a crowding setting. Monotonically increasing Type A masking functions observedfor small spacings and large eccentricities indicate that the integration of information from target and flankers underlies crowding. Decreasing masking functions obtained for large spacings and small eccentricities relate processes of crowding to those contributing to Type B masking. In addition, Type B masking was more frequent with letter-like nonletter flankers than with letter flankers, suggesting that Type B masking, just like crowding over large areas, is due to higher level interactions. The rapid decrease of the effects of interletter spacing and eccentricity with increasing SOA indicates that positional information is transient.     

Taiwanese members' report of verbal interactions and their relations to demographic variables in the group counseling process

The purpose was to examine differences in verbal interactions during the group counseling process and the relationship between perceived verbal interactions and members' demographic variables. 42 participants were recruited and randomly assigned to one of four counseling groups. Based on the Hill Interaction Matrix, Quadrant 4 verbal interactions, consisting of Speculative and Confrontative verbal behaviors in Personal and Relationship levels, were perceived significantly more often at the closing stage than at the initial stage. Furthermore, the perceived verbal interactions were related to the demographic variables of sex, educational level, and group experience, but not acquaintanceship. The findings suggested that the higher ratings of perceived Speculative and Confrontative verbal behaviors and the lower ratings of Assertive and Silence verbal interactions must be interpreted cautiously from a cross-cultural perspective, especially in Asian cultures.     

Linear correlations between sets of variables

While the traditional multiple correlation coefficient appears to be inherently an asymmetrical statistic, it is actually a special case of a more general measure of linear relationship between twosets of variables. Another symmetric generalization of linear correlation is to the total relatednesswithin a set of variables. Both of these developments rest upon thegeneralized variance of a multivariate distribution, which is seen to be the fundamental concept of linear correlational theory.     

Requencies and relations of body piercing and sexual experience in college students

This research examined the relation between having a body piercing and having engaged in premarital sexual intercourse. Data were gathered from a convenience sample of 450 college students. 72% were women; 85% were ages 18 to 22 years (M=20.9, SD=4.5), 80% were Euro-American. Women with piercings reported substantively and significantly greater frequency of sexual activity than college students without piercings. There were no significant differences in sexual experience between men with piercings and those without. These findings differ from previous research comparing the sexual activity of college students with and without tattoos.
