Combining Methodologies in the Construct Validation Process: An Empirical Illustration

Confirmatory Factor Analysis (CFA) has received considerable support as a methodology for assessing construct validity. As with other methodologies, however, numerous problems can be encountered when using CFA to assess construct validity. Given the limitations of the CFA, Multitrait-Multimethod (MTMM), and analysis of variance (ANOVA) methodologies, a set of guidelines was developed. The guidelines recommend that the characteristics of the data set be used to determine how the three alternative construct validation methodologies can be used in combination. Examples from the research literature are discussed in order to demonstrate the application of these guidelines.     

Creating your own hostile environment: a laboratory examination of trait aggressiveness and the violence escalation cycle

A dyadic interactive aggression paradigm tested hypotheses from the General Aggression Model about how trait aggressiveness can create behaviorally hostile social environments. Pairs of college student participants competed in a modified reaction time task in which they repeatedly delivered and received each other's punishments. The trait aggressiveness of both participants influenced the punishment intensities (aggression level) set by each member of the dyad on later trials. Furthermore, there was a pattern of escalation from early to later trials. These trait aggressiveness effects (both self and partner) on later aggressive behavior were largely mediated by partner aggression levels during early trials. Results also suggested two aggressive motives--hostile and instrumental--resulted from high partner aggression during early trials and these motives partially mediated the effects of trait aggressiveness and of early trial aggression on later aggressive behavior.     

The Temporal Automated System for Taste Experiments (TASTE).

We describe a new, open flow device for presenting taste stimuli to human subjects under controlled conditions of timing. The device delivers each stimulus as a mist to the participant's tongue through one of 16 nozzles attached to a linear slide. Software controls the position of the slide, the duration of the stimulus, and the duration of the pre- and poststimulus water rinses and records the responses of the participant. Temporal characteristics of this system make it especially applicable to studies on the role of attention in taste perception.     

Black Adolescent Girls: Do Gender Role and Racial Identity: Impact Their Self-Esteem?

This study was designed to explore Black adolescent girls' gender roles, racial identity, and self-esteem. These variables have not been examined together in a study of Black girls, yet studies of girls from other racial/cultural groups have demonstrated significant relationships. This type of exploration is important because Black girls do not experience the same declines in self-esteem as girls from other racial/cultural groups. Gender role orientation and racial identity have been put forth as possible explanations for Black girls' bolstered levels of self-esteem. Results indicated that Black girls with androgynous and masculine characteristics reported high levels of self-esteem. The results also indicated that Black girls with internally defined Black racial identity attitudes reported high levels of domain-specific self-esteem. In addition, androgyny was associated with high scores on internalization (Black racial identity).     

Walking through doorways differentially affects recall and familiarity

Previous research has reported that walking through a doorway to a new location makes memory for objects and events experienced in the previous location less accurate. This effect, termed the location updating effect, has been used to suggest that location changes are used to mark boundaries between events in memory: memories for objects encountered within the current event are more available than those from beyond an event boundary. Within a computer‐generated memory task, participants navigated through virtual rooms, walking through doorways, and interacting with objects. The accuracy and their subjective experience of their memory for the objects (remember/know and confidence) were assessed. The findings showed that shifts in location decreased accurate responses associated with the subjective experience of remembering but not those associated with the experience of knowing, even when considering only the most confident responses in each condition. These findings demonstrate that a shift in location selectively impacts recollection and so contributes to our understanding of boundaries in event memory.     

Father Involvement and Coparenting Behavior: Parents' Nontraditional Beliefs and Family Earner Status as Moderators

This study investigated relations between father involvement in caregiving and play and coparenting behavior using self-report and observational data from 80 two-parent families of preschool-aged children, and examined parents' nontraditional beliefs about fathers' roles and family earner status as moderators of these relations. Results indicated that greater father involvement in caregiving and play was associated with less observed undermining coparenting behavior in dual-earner families. Conversely, greater father involvement in caregiving was associated with less perceived supportive and greater perceived undermining coparenting behavior in single-earner families. Father involvement in play was not related to coparenting behavior among single-earner families. This study highlights the importance of considering parental employment patterns and the multidimensional nature of fathering behavior when studying fathering and coparenting.     

Programming generalization and maintenance of treatment effects across time and across settings

Effects of three experimental and one control strategy were investigated in facilitating generalization and maintenance of treatment effects after two months in a token-economy classroom. At the conclusion of treatment, subjects were randomly assigned to one of three maintenance strategies or a control group and returned to their regular classrooms. The maintenance strategies were peer reprogramming, equating stimulus conditions between the experimental and regular classrooms, and teacher training in behavior management techniques. The maintenance strategies were implemented in the regular classroom for a two-month period and then terminated. Results indicated a powerful treatment effect produced by the token economy. Behavior maintenance effects following treatment were also obtained. The mean per cent appropriate behavior for the peer reprogramming and equating stimulus conditions strategies was significantly greater than the mean for the control subjects. The teacher training and control group means were not significantly different.     

Perirhinal cortical contributions to object perception

The traditional theory of the medial temporal lobe (MTL) memory system asserts that the primate MTL (hippocampus, perirhinal, entorhinal and parahippocampal cortices) is exclusively involved in consolidating declarative memories. However, several recent reports have directly challenged this dogma by arguing that MTL structures also contribute to perception. Controversy remains as many of the behavioural tasks used have confounded memory with perception. We review the evidence here and highlight new studies in humans and macaques that indicate a perceptual role for MTL in the absence of such confounds. We argue that the challenge to MTL memory system theory is substantiated and that the implications are considerable, namely that most psychologists and neuroscientists have held a fundamentally flawed view of how memory is implemented in the brain.
