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.     

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.     

A Brief Report on Predicting Self-Harm: Is It Gender or Abuse that Matters?

Self-harm, which consists of nonsuicidal self-injury and attempted suicide, is a public health problem that is not well understood. There is conflicting evidence on the role of gender in predicting self-harm. Abuse history also is a potentially relevant factor to explore, as it is related to both gender and self-harm. In this study, we hypothesized that abuse history, as opposed to gender, would predict self-harm. Three hundred and ninety-seven undergraduates completed a self-report survey that assessed abuse history, nonsuicidal self-injury, and attempted suicide. The results suggested that abuse history predicted nonsuicidal self-injury and attempted suicide. These findings can inform clinical interventions as they reinforce the importance of including abuse history in the conceptualizations and treatment of self-harm.     

Perception of randomness and predicting uncertain events

Using randomly generated sequences of binary events we asked participants to make predictions about the next event. It turned out that while predicting uncertain events, people do not behave unsystematically. Our research identifies four types of relatively consistent strategies for predicting uncertain binary events: a strategy immune to short-run sequential dependencies consisting of the persistent prediction of long-run majority events, hereafter called the long-run momentum strategy; a strategy immune to short-run sequential dependencies consisting of the persistent prediction of long-run minority events, called the long-run contrarian strategy; a strategy sensitive to short-run sequential dependencies consisting of the prediction of short-run majority events, called the short-run momentum strategy; and a strategy sensitive to short-run sequential dependencies consisting of the prediction of short-run minority events, called the short-run contrarian strategy. When the character of events remains unknown, the most common strategy is the short-run momentum strategy. With the increase of a perceived randomness of the situation, people tend more often to use the short-run contrarian strategy. People differ in their general beliefs about the continuation or reversal of a trend in various natural and social processes. Trend believers, when facing sequences of binary events commonly perceived as random, tend to use momentum strategies, whereas those who believe in the trend's reversal tend to use contrarian strategies.     

The telltale face: Possible mechanisms behind defector and cooperator recognition revealed by emotional facial expression metrics

In this study, we investigated the role of facial cues in cooperator and defector recognition. First, a face image database was constructed from pairs of full face portraits of target subjects taken at the moment of decision‐making in a prisoner's dilemma game (PDG) and in a preceding neutral task. Image pairs with no deficiencies (n = 67) were standardized for orientation and luminance. Then, confidence in defector and cooperator recognition was tested with image rating in a different group of lay judges (n = 62). Results indicate that (1) defectors were better recognized (58% vs. 47%), (2) they looked different from cooperators (p < .01), (3) males but not females evaluated the images with a relative bias towards the cooperator category (p < .01), and (4) females were more confident in detecting defectors (p < .05). According to facial microexpression analysis, defection was strongly linked with depressed lower lips and less opened eyes. Significant correlation was found between the intensity of micromimics and the rating of images in the cooperator‐defector dimension. In summary, facial expressions can be considered as reliable indicators of momentary social dispositions in the PDG. Females may exhibit an evolutionary‐based overestimation bias to detecting social visual cues of the defector face.
