Explorations of familiarity produced by words with specific combinations of letters

We explore familiarity-based recognition using a paradigm devised by Parkin et al. (2001). The task consists of the creation of two lists of words written with one of two different subsets of letters of the alphabet. We manipulated study time (50, 100, 200, 500 ms per word) of words with different letter probabilistic structure to those originally used by Parkin et al. Letter-based familiarity responding was robust and present even at rates producing otherwise chance performance. A second experiment and structural equation modelling led us to interpret the results from the point of view of a theory that takes into account the processing of similarities and differences (Hunt & MacDaniel, 1993). Finally, our data indicate that the experimental procedure devised by Parkin et al. is an excellent tool with which to study familiarity, once the structure of probabilities of individual letters is considered as the key factor in inducing the effect.     

"If …": Satisficing algorithms for mapping conditional statements onto social domains

People regularly use conditional statements to communicate promises and threats, advices and warnings, permissions and obligations to other people. Given that all conditionals are formally equivalent--"if P, then Q"--the question is: When confronted with a conditional statement, how do people know whether they are facing a promise, a threat, or something else? In other words, what is the cognitive algorithm for mapping a particular conditional statement onto its corresponding social domain? This paper introduces the pragmatic cues algorithm and the syntactic cue algorithm as partial answers to this question. Two experiments were carried out to test how well these simple satisficing algorithms approximate the performance of the actual cognitive algorithm people use to classify conditional statements into social domains. Conditional statements for promises, threats, advices, warnings, permissions, and obligations were collected from people, and given to both other people and the algorithms for their classification. Their corresponding performances were then compared. Results revealed that even though these algorithms utilised a minimum number of cues and drew only a restricted range of inferences from these cues, they performed well above chance in the task of classifying conditional statements as promises, threats, advices, warnings, permissions, and obligations. Moreover, these simple satisficing algorithms performed comparable to actual people given the same task.     

Word naming in Spanish

Studies on the factors that determine word naming speed have been conducted in a number of languages. In this study two objectives were pursued: (1) to contrast the effects of the variable of age of acquisition with the different measures of frequency of use (adult written frequency, child written frequency, cumulative frequency, and frequency trajectory), and (2) to verify which variables determine reading latencies in a language with a completely transparent reading system (Spanish). For these purposes, 53 native speakers of Spanish read aloud 240 words for which values were available of the main lexical, phonological, and semantic variables. The results of the regression analyses showed that the best predictors of reading times were length (measured in terms of both number of letters and number of syllables) and subjective age of acquisition (AoA). The different frequency measures correlated significantly with the response latencies but were not longer significant in the regression analyses. Semantic variables (familiarity and imageability) had the smallest effects on reading speed. The comparison of the results obtained in this study with those reported for other languages offers some conclusions about the effects of orthographic systems on word naming.     

Involuntary future projections are as frequent as involuntary memories,but more positive

Mental time travel (MTT) is the ability to mentally project oneself into one’s personal past or future, in terms of memories of past events or projections of possible future events. We investigated the frequency and valence of involuntary (spontaneously arising) MTT in the context of high trait worry. High (N = 18) and low (N = 16) worriers recorded the frequency and valence of involuntary memories and future projections using a structured notebook and completed measures probing individual differences related to negative affectivity. Involuntary future projections were as frequent as involuntary memories. We found a positivity bias for both past and future MTT, in that fewer negative events were reported than positive or neutral ones. This positivity bias was greater for future than for past events. Individual differences related to negative affectivity were positively associated with the proportion of negative events, indicating a reduced positivity bias in individuals with a general tendency to experience negative affect.     

Spiritual Transcendence and Mental Health of Psychotherapists and Religious Professionals in a Hungarian Adult Sample

In this study we examine whether components of spiritual transcendence can explain individual differences in mental health in a Hungarian adult sample (N = 583), with a special focus on the associations in two subsamples, religious professionals and psychotherapists. Using the Spiritual Transcendence Scale (STS), we found that religious professionals presented higher Prayer Fulfillment and Universality than psychotherapists; however, members of both professional groups scored higher than other professionals on these dimensions. By contrast, psychotherapists were superior to religious professionals in Connectedness. Moreover, higher Universality predicted better mental health, even after controlling for gender, age, profession, and basic personality traits. No interaction effects were found between profession and the subscales of the STS. Results suggest that the potential mental health benefits of spirituality, especially in form of a universal view of existence, are equally present in both specific professions and in the general sample, whereas the professions themselves still reflect differences both in spirituality and in well-being.     

The effects of perpetrator age and abuse disclosure on the relationship between feelings provoked by child sexual abuse and posttraumatic stress

Abstract

The present study examined the relationship between feelings provoked by child sexual abuse (CSA) and posttraumatic stress disorder (PTSD) symptom scores in a sample of 163 female survivors of CSA. Finkelhor and Browne's traumagenic dynamics model was applied. The interactive effects of provoked feelings with perpetrator age and the existence of abuse disclosure were also studied. Results showed an overall relationship between feelings provoked by CSA and PTSD symptom scores. Feelings of stigma, betrayal, and powerlessness as a result of CSA were associated with PTSD symptom score when the entire group of CSA victims was analyzed. The role of traumatic sexualization was relevant only when analyzed in interaction with the age of the perpetrator and disclosure. The relationship between traumatic sexualization and PTSD symptom scores was only significant when the abuse was committed by an adult perpetrator and when a disclosure was made during the time of abuse, or a short time after the abuse had occurred.     

ANXIETY SENSITIVITY AND TRAIT-SYMPTOM MEASURES OF ANXIETY AND DEPRESSION

The Icelandic version of the Anxiety Sensitivity Index was investigated in two studies of college students. A principal components analysis of ASI scores from both studies (N=718) yielded three components similar to what has been found previously: Psychological Concerns, Physical Concerns and Social Concerns. In the first study the relationship between the ASI and trait anxiety was investigated. It was analysed at the level of the total scales but also at the level of subscales of both instruments. Two subscales of the STAI, measuring respectively Anxiety-trait and Depression-trait, were used as well as the Psychological Concerns and Physical Concerns subscales of the ASI. In a second study the relationships between ASI and its subscales and two symptom measures of anxiety and depression were addressed. ASI was in both studies more strongly related to the anxiety than the depression scales. Also, in both studies the Physical Concerns subscale of the ASI was more strongly related to anxiety than to depression, whereas the Psychological Concerns subscale was equally related to anxiety and depression. Taken together the studies support the notion of different relationships between different aspects of anxiety sensitivity, and anxiety and depression as traits, cognitive symptoms and mood related symptoms.     

Private Speech in Illiterate Adults: Cognitive Functions, Task Difficulty, and Literacy

Children’s private speech has been widely studied among children, but it is clear that adults use private speech as well. In this study, illiterate adults’ private speech during a “school-like” task was explored as a function of literacy level and task difficulty in a sample of 126 adults enrolled in a public literacy program. A main effect for literacy level was found—private speech was more internalized and less externalized among adults with higher literacy levels. Externalized private speech was more frequently observed among illiterate adults engaged in the most difficult task. Private speech served cognitive functions as indicated by the proportion of self-regulatory private speech and the proportion of private speech preceding actions being higher in the advanced literacy group and among illiterate adults doing the easier task. Internalized private speech, self-regulatory private speech, and private speech preceding action were each positively correlated with performance and negatively correlated with time to complete the task. The use of private speech in illiterate adults appears to be linked to the mastery of cultural experiences, such as literacy, similar to the self-talk of children.
