What do people think about when answering questionnaires to assess unrealistic optimism about skin cancer? A think aloud study

There is little information concerning what people think about when completing questionnaires that assess perceptions of risk, and even less for questionnaires assessing unrealistic optimism. The thoughts of 40 participants who displayed unrealistic optimism about risks of skin cancer were elicited using think aloud methods, when completing both direct and indirect ratings of unrealistic optimism. The most common thoughts overall concerned exposure to the sun, and features such as skin colouring. Thoughts concerning prevalence, reasons for risky behaviour and admissions of ignorance were more common for indirect measures of unrealistic optimism than for direct measures. The direct unrealistic optimism measures yielded more optimistic ratings for those participants who did not mention symptoms or signs of skin damage, and those who mentioned thoughts about prevalence. Participants seem to be drawing upon different sources of information when completing superficially similar direct and indirect measures of unrealistic optimism, which may explain why these measures are usually only modestly associated. People do not seem to think about numerical probabilities when estimating risk, but instead appear to focus on issues such as exposure to risk, and concrete bodily symptoms and signs. This may at least partially explain why attempts to influence behaviour by providing probabilistic information are generally unsuccessful.     

Notational Variance and Its Variants

What does it take for two logics to be mere notational variants? The present paper proposes a variety of different ways of cashing out notational variance, in particular isolating a constraint on any reasonable account of notational variance which makes plausible that the only kinds of translations which can witness notational variance are what are sometimes called definitional translations.

     

Ethnicity-Related Stressors and Mental Health in Latino Americans: The Moderating Role of Parental Racial Socialization

The current study examined the moderating role of proactive and reactive parental racial socialization on the relationship between Latino American college students' mental health and 3 ethnicity-related stressors: perceived racial discrimination, stereotype confirmation concern, and own-group conformity pressure. In hierarchical regression, greater stereotype confirmation concern predicted more mental distress in 105 Latino American college students. Both proactive and reactive racial socialization moderated the effect of own-group conformity pressure on anxiety and loss of behavioral/emotional control. Specifically, greater proactive and reactive racial socialization predicted more mental distress under greater own-group conformity pressure. Findings are interpreted in a college environment of ethnic diversity and a context of acculturative stress.     

Anxiety sensitivity, conscious awareness and selective attentional biases in children

The current study investigated whether physical anxiety sensitivity (AS) is associated with selective attentional biases to affective stimuli in children. The dot-probe paradigm was used to examine the deployment of attention towards words pertaining to anxiety symptomatology, socially threatening words, and positive words, in samples of 8-10-year-old children. Word pairs were presented under both masked and unmasked conditions. Irrespective of masking, children high in physical AS displayed an attentional vigilance for emotional words relative to neutral words, whereas those low in physical AS displayed a relative avoidance of such material. The results of this study are interesting as they not only suggest the presence of automatic AS-related biases in childhood, but that this is a general emotionality bias rather than one related to specific anxiety-related stimuli.     

The development of ethnic identity during adolescence

The development of ethnic identity is a critical facet of adolescence, particularly for adolescents of color. In order to examine the developmental trajectory of ethnic identity, African American, Latino American, and European American early and middle adolescents (N = 420) were assessed over 3 years. Two components of ethnic identity were assessed--group-esteem was found to rise for both early and middle adolescents; exploration rose for middle adolescents. African Americans and Latino Americans were lower in group-esteem but have greater increases than European Americans, particularly across a school transition. The course of ethnic identity development during early and middle adolescence, the role of school context, and the variability in developmental trajectories among racial and ethnic groups are discussed.     

Observing the preservation and decline of abilities in dementias

The Brief Cognitive Rating Scale facilitated observation of the preservation and decline of abilities due to dementias among 73 female and 52 male residents at nursing homes in a northeastern and southwestern state. They ranged in age from 41 to 102 years (M=78, SD = 10.5). Dementia diagnoses included presenile Alzheimers, senile Alzheimers, Vascular Dementia, Dementia secondary to Huntington's Disease, Dementia due to Pick's Disease, and Korsakoff Dementia secondary to chronic alcoholism. Their ratings on tasks of the scale were submitted to an order analysis procedure to explore the order of decline and preservation of abilities. Results for these nursing home residents show an apparent order: loss singly or concurrently of the abilities of concentration and recent memory, followed by past memory and functioning and self-care that also appeared to be unpredictably lost or preserved singly or concurrently by different individuals, and, finally, by orientation that was preserved in 82% of the subjects.     

Anxiety sensitivity: the role of conscious awareness and selective attentional bias to physical threat

Selective attentional biases were examined amongst individuals varying in levels of physical anxiety sensitivity. The dot-probe paradigm was used to examine attention towards anxiety symptomatology, social threat and positive words. Stimuli were presented above (unmasked) and below (masked) the level of conscious awareness. High physical anxiety sensitivity was associated with attentional vigilance for anxiety symptomatology words in both unmasked and masked conditions. For positive words, however, those high in anxiety sensitivity were found to avoid such stimuli when they were masked, whereas they exhibited a relative vigilance when unmasked. If the differences between awareness conditions are reliable, then the impact of the automatic vigilance for threat might be modified by conscious attempts to direct attention towards other types of stimuli.     

The computational modeling of analogy-making

Our ability to see a particular object or situation in one context as being 'the same as' another object or situation in another context is the essence of analogy-making. It encompasses our ability to explain new concepts in terms of already-familiar ones, to emphasize particular aspects of situations, to generalize, to characterize, to explain or describe new phenomena, to serve as a basis for how to act in unfamiliar surroundings, and to understand many types of humor. Within this framework, the importance of analogy-making in modeling cognition becomes clear.     

Expressive power, mood, and actuality

In Wehmeier (J Philos Log 33:607–630, 2004) we are presented with the subjunctive modal language, a way of dealing with the expressive inadequacy of modal logic by marking atomic predicates as being either in the subjunctive or indicative mood. Wehmeier claims that this language is expressively equivalent to the standard actuality language, and that despite this the marked-unmarked dichotomies are not the same in the two languages. In this paper we will attend to Wehmeier’s argument that this is the case, and show that this conclusion rests on what might be considered an uncharitable stipulation concerning what it is for a formula in the actuality language to be true in a model.
