A depressive symptom scale for the California Psychological Inventory: construct validation of the CPI-D

To facilitate life span research on depressive symptomatology, a depressive symptom scale for the California Psychological Inventory (CPI) is needed. The authors constructed such a scale (the CPI-D) and compared its psychometric properties with 2 widely used self-report depression scales: the Beck Depression Inventory and the Center for Epidemiological Studies Depression Scale. Construct validity of the CPI-D was examined in 3 studies. Study 1 established content validity, classifying CPI-D items into Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition depressive symptoms. Study 2 used 3 large samples to gather evidence for reliability and validity: correlational analyses demonstrated alpha reliability and convergent and discriminant validity; factor analysis provided evidence for discriminant validity with anxiety; and regression analyses demonstrated comparative validity with existing standard PI scales. Study 3 used clinician ratings of depression and anxiety as criteria for external validity.     

The influence of distractor-only prime trials on the location negative priming mechanism

Two experiments were conducted that examined the influence of distractor-only prime trials on the "location" negative priming (NP) effect. In all experiments, the probe trial always lacked a distractor. We showed that the predictable absence of a probe distractor caused the elimination of the location NP effect when the prime trial contained both a target and a distractor event (T + D-->T), but not when the prime contained only a to-be-ignored distractor event (D-->T) (Milliken, Tipper, Houghton, & Lupianez, 2000). The preservation of the NP effect seen with the distractor-only prime trials (D-->T) was not the result of its lacking a prime-trial selection, nor was it the consequence of its representing a higher level of episodic similarity than the T + D-->T condition. Finally, the location NP effect observed for the D-->T condition is seemingly consistent with the view that location NP and the inhibition-of-return effects share a common underlying process (Milliken et al., 2000).     

Adult helping qualities preferred by adolescents

Most studies of therapeutic alliance have focused on adult populations and been written from the therapist's perspective. Thus, there is a clear need for studies of therapeutic alliance that focus on adolescent populations from the perspective of the adolescents. The current study is an exploratory process investigation using a focus group methodology with a nonclinical sample of adolescents to determine which traits in adults might foster alliance, with the assumption that the same traits would apply to therapeutic settings. A content analytic approach was used and 12 adult qualities found to be preferred by adolescents from most to least cited were: respect, time shared, openness, role characteristics, recognition, guidance, identification, trust, freedom, like/ dislike, responsibility, and familiarity.     

Global model analysis by parameter space partitioning

To model behavior, scientists need to know how models behave. This means learning what other behaviors a model can produce besides the one generated by participants in an experiment. This is a difficult problem because of the complexity of psychological models (e.g., their many parameters) and because the behavioral precision of models (e.g., interval-scale performance) often mismatches their testable precision in experiments, where qualitative, ordinal predictions are the norm. Parameter space partitioning is a solution that evaluates model performance at a qualitative level. There exists a partition on the model's parameter space that divides it into regions that correspond to each data pattern. Three application examples demonstrate its potential and versatility for studying the global behavior of psychological models.     

Effects of nicotine deprivation on craving response covariation in smokers

Most models of craving propose that when cravings are strong, diverse responses--thought to index an underlying craving state--covary. Previous studies provided weak support for this hypothesis. The authors tested whether nicotine deprivation affects degree of covariation across multiple measures related to craving. Heavy and light smokers (N = 127) were exposed to smoking cues while either nicotine deprived or nondeprived. Measures included urge ratings, affective valence, a behavioral choice task assessing perceived reinforcement value of smoking, and smoking-related judgment tasks. Results indicated higher correlations in the nicotine-deprived than in nondeprived group. The measures principally responsible for this effect loaded onto a single common Craving factor for nicotine-deprived but not nondeprived smokers. These findings suggest that, under certain conditions, measures of craving-related processes covary.     

The interpersonal expression of perfection: perfectionistic self-presentation and psychological distress

A concept involving the interpersonal expression of perfection, perfectionistic self-presentation, is introduced. It is argued that perfectionistic self-presentation is a maladaptive self-presentational style composed of three facets: perfectionistic self-promotion (i.e., proclaiming and displaying one's perfection), nondisplay of imperfection (i.e., concealing and avoiding behavioral demonstrations of one's imperfection), and nondisclosure of imperfection (i.e., evading and avoiding verbal admissions of one's imperfection). Several studies involving diverse samples demonstrate that perfectionistic self-presentation is a valid and reliable construct and a consistent factor in personal and interpersonal psychological distress. It is argued that the need to promote one's perfection or the desire to conceal one's imperfection involves self-esteem regulation in the interpersonal context.     

The elusive nature of self-measurement: the self-construal scale versus the twenty statements test

In the present study, the authors compared 2 frequently used measures to operationalize the construct of the self, namely, the Self-Construal Scale (SCS; T. M. Singelis, 1994) and the Twenty Statements Test (TST; M. Kuhn & T. S. McPartland, 1954), in a sample of 324 male and female undergraduate psychology students of diverse ethnocultural backgrounds. Results demonstrated low intercorrelations between the 2 measures, suggesting that the qualitative and quantitative measures did not evaluate the same construct. A factor analysis of the SCS scale revealed 3 constructs-an independent construct, an interdependent construct, and a power distance or hierarchy construct. Implications for future research included the need for ongoing work in identifying and measuring the constructs of the self.     

Inhibition of return and manual pointing movements

To examine whether the motor inhibition of return (IOR) postulated by Taylor and Klein (1998, 2000) generalizes to manual guided movements or is restricted to saccadic responses, the following three experiments were conducted. The first experiment combined peripheral cues (which generate IOR) with four types of manual responses made to central targets (central arrow indicating the response location). The responses were made on a touch-screen and were the equivalent of either a detection keypress, a choice keypress, a detection-guided pointing movement, or a choice-guided pointing movement. No IOR was found for any of the responses. The second experiment replicated the main result under eye fixation control. In Experiment 3, peripheral cues and peripheral targets were used, and IOR was present in all responses. Overall, these finding suggest that motor-based IOR is restricted to the oculomotor system. Implications for motor-based IOR and attention-based IOR are discussed.     

Demythologizing the emotions: adaptation,cognition, and visceral representations of emotion in the nervous system

This article highlights four issues about the neurobiology of emotions: adaptation vs. dysfunction, peripheral and central representations of emotion, the regulation of the internal milieu, and whether emotions are cognitive. It is argued that the emotions evolved to play diverse adaptive roles and are biologically vital sources of information processing. They were not designed as pieces of pathology, though they certainly can underlie some psychophathologies. Emotions are, in part, appraisal systems that are operative at numerous level of the nervous system from the brainstem to the cortex. Like other information processing systems they are not perfect cognitive systems. Emotional systems often utilize somatic and visceral information for appraisals of events to facilitate decisions of whether to approach or avoid objects. The neural systems of emotions traverse the entire neural axis and are linked to the regulation of the internal milieu. Thus, in addition to the experiential aspects of emotions, emotions embody appraisal systems that are pervasive to all levels of the brain to facilitate function, adaptation, and survival.     

Inhibition of return spreads across 3-D space

Focusing attention to a location in 3–D space operates much the same as in 2–D space. Attending a location in 2–D space is followed by a selective inhibitory aftereffect known as inhibition of return (IOR). Here, we report the results of two 3–D reflexive cuing studies in which depth was defined by binocular disparity. As has been shown before, attentional cuing was specific for x–y–z locations. However, the present results show that IOR is not depth specific. After a specific location in x–y–z is cued, IOR occurs for the depth plane in front of and behind the cued location. The finding that IOR spreads across depth planes may be related to how inhibited locations are encoded in the superior colliculus. We argue that the functional role of a depth–blind IOR is to bias attention against going back to any part of a previously attended object.
