Problems with single interest scales: Implications of the general factor

The presence of the general factor in interest and self-efficacy assessment and its meaning are reviewed. The general factor is found in all interest and self-efficacy assessment and has been viewed as (a) a nuisance factor with little effect on assessment, (b) a variable having substantive meaning and thus worthy of including in interpretation, and (c) as systematic bias that distorts the interpretation of the meaning of assessments. The premise of this article is that each interpretation is correct but only depending upon the context of the assessment. The main implication is that narrow single content interest scales are very subject to contaminating effects of the general factor making interpretation very difficult. Methods of correcting this contamination are presented.     

Huntington Disease: Who Seeks Presymptomatic Genetic Testing,Why and What are the Outcomes?

The aims of this study were to: 1) quantify the characteristics of those seeking presymptomatic testing for HD, 2) identify their motivations for testing, 3) quantify the waiting times between the various steps within the testing process, and 4) quantify the outcomes of testing at a large state-wide genetic testing center in Australia. A review of medical charts for all referrals for presymptomatic testing of Huntington disease received over a 4 year period (2006–2010) was undertaken. A total of 152 cases met the study inclusion criteria; the mean age was 39 years, 46 % were male and 61 % underwent genetic testing. Of the males who were tested there was a non-significant trend towards having an affected mother vs father (62 %, p?=?0.09), whereas females tested were just as likely to have an affected mother or father. The most frequently cited reasons for seeking testing were “family planning”, “plan future”, and “need to know”. Some 11 % deferred testing following the psychological assessment. Of those at 50 % prior risk, 57.5 % tested positive; this was higher than expected and much higher than reported in other studies. The median times from referral to initial appointment, and then to results was 69 days and 144 days respectively. Overall, this review of medical charts shows the depth of information obtainable from routinely collected data and revealed that a high proportion of patients tested positive for HD at this centre.     

The Impact of Feminist Attitudes on the Relation between Racial Awareness and Racial Identity

This study examined the role of liberal and inclusive feminist attitudes in the development of a positive racial identity in a sample of White female undergraduates in the Midwestern United States. Participants (N?=?90) provided self-report data on their racial awareness, liberal and inclusive feminist attitudes, racial identity and demographic information. The main research question was how and to what extent liberal and inclusive feminism influence the relationship between racial awareness and racial identity. Building on conceptual scholarship on identity theory and the intersectionality, results indicated that the relation between racial awareness and racial identity was partially mediated by inclusive feminist attitudes but not by liberal feminist attitudes. The results suggest that a specific type of feminism, which takes into account the experience of race, plays a significant role in our understanding of how White women develop a positive White identity. Results highlight the intersection of race and gender in college student development and have potential implications for administrative responses to student adjustment in increasingly diverse college environments.     

‘Give Me a Reason to Live!’ Examining Reasons for Living Across Levels of Suicidality

Scholarly research focusing on social psychological factors (e.g. mental health) and social environmental factors (e.g. childhood trauma) has found these measures to be correlated with suicidality. However, such literature has tended to overlook what may impact one’s reasons for living. Using a sample of over 1,200 students from a Canadian university, the goal of the current study is to empirically test, by employing multivariate nested regression models (by levels of suicidal behaviour), known and relative unknown correlates with reasons for living, with a particular focus on strength of religious faith, which is a well-known predictor for suicidality, but less studied as a reason for living. Results show that, among students with serious suicidal ideation and/or a previous suicide attempt, the strongest predictor for student’s reasons for living was strength of religious faith. Strength of religious faith has seldom been acknowledged or identified as an important measure in assessing one’s reasons to live. These findings have implications for the role of religiosity among suicidality research, especially studies that focus on reasons for living.     

Dishabituation in Aplysia can involve either reversal of habituation or superimposed sensitization

Dishabituation has been thought to be due either to reversal of the process of habituation or to a second process equivalent to sensitization superimposed on habituation. One way to address this question is by testing whether dishabituation and sensitization can be dissociated. Previous studies using this approach in Aplysia have come to different conclusions about the nature of dishabituation, perhaps because those studies differed in many respects, including (1) whether they also observed transient behavioral inhibition, and (2) whether they used test stimuli that activated the LE siphon sensory neurons or as yet unidentified sensory neurons. To attempt to resolve the apparent contradictions between the previous studies, we have explored the importance of these two factors by performing a parametric study of dishabituation and sensitization of gill withdrawal in a simplified preparation that does not exhibit transient behavioral inhibition, using two different test stimuli that are known to activate the LE (Touch) or unidentified (Not Touch) sensory neurons. We find that dishabituation and sensitization in this preparation have similar time courses and generally similar functions of shock intensity. However, under one condition, with the Not Touch stimulus 2.5 min after the shock, dishabituation has a reverse effect of shock intensity. Additional analyses suggest that dishabituation with the Not Touch stimulus 2.5 min after the shock is due to reversal of habituation, whereas 12.5 min after the shock, dishabituation is due to superimposed sensitization. These results thus suggest that dishabituation may involve either process in the same preparation, and begin to define the conditions that favor one or the other.     

Taste-aroma interactions in a ternary system: a model of fruitiness perception in sucrose/acid solutions

Cross-modal interactions between aroma, sweetness, and acidity were studied. A series of samples was presented to trained panelists who assessed strawberry flavor intensity using magnitude estimation with a reference modulus. The delivery of aroma stimuli from the different solutions was measured by monitoring exhaled breath using atmospheric pressure chemical ionization-mass spectrometry to determine whether there were any physicochemical effects on volatile release; no significant differences were noted. Three-dimensional predictive models were built to describe perceived strawberry flavor intensity as a function of concentrations of sucrose, acid, and volatiles. Analysis of the data identified two groups of panelists with different responses: For Group 1, increasing sucrose and/or acid levels also increased the perceived flavor intensity. For Group 2, changing sucrose concentrations had little effect, but increasing acid and/or volatile levels did. The results show different effects of organic and inorganic acids on perception, as well as clear interactions between the modalities of taste (sugar and acid) and aroma. The clustering of panelists' responses suggests that this phenomenon may depend on prior associations between the fruity flavor and the tastants.     

Relation of interest and self-efficacy occupational congruence and career choice certainty

A sample of 2145 adults completed the Personal Globe Inventory (PGI) as well as indicating their occupational choice and the certainty of this choice. The PGI yielded interest and self-efficacy scores and these were used with the occupational choice to calculate a congruence score for interests and one for efficacy. The prediction of career certainty by each congruence measure and their interaction was examined using hierarchical regression. The results indicated that while both interest and efficacy congruence were related to career certainty, efficacy congruence did not add to prediction above that obtained using interests congruence alone, however there was a substantial interaction. The agreement of interest congruence and efficacy congruence was related to a strong positive relation between congruence and certainty; whereas low agreement between interest and efficacy congruence was related to a non-significant relation between congruence and certainty. The results demonstrate the need to focus on both interest and efficacy and their agreement in our assessments and interventions.     

Countertransference as a prototype: The development of a measure

Countertransference is a concept that is widely acknowledged, but there exists little definitional consensus, making research in the area difficult. The authors adopted a prototype theory (E. H. Rosch, 1973a, 1973b; see C. B. Mervis & E. Rosch, 1981, for a review) to examine this construct because it conceptually fits well with constructs that elude explicit definition. In Study 1, 45 experienced psychologists highly agreed with the prototypicality of 104 different examples of countertransference providing support for the presence of a prototype. In Study 2, the usage of this prototype in a sample of 35 trainees was related to ability to perceive countertransference in a case example drawn from the literature and positively correlated with self-reports of their experiences of countertransference but not with their self-reported ability to manage countertransference once it was manifest. Implications for training and research are discussed.
