Reading comprehension and understanding idiomatic expressions: a developmental study

The aim of the present study was to investigate idiom comprehension in school-age Italian children with different reading comprehension skills. According to our hypothesis, the level of a child's text comprehension skills should predict his/her ability to understand idiomatic meanings. Idiom comprehension in fact requires children to go beyond a simple word-by-word comprehension strategy and to integrate figurative meaning into contextual information. In a preliminary phase, we used a standardized battery of tests (Cornoldi & Colpo, 1998) to assess the ability of second graders and fourth graders to comprehend written texts. Three groups were identified at each age level: good, medium, and poor comprehenders. Children were then presented with familiar idiomatic expressions which also have a literal meaning (e.g., "break the ice"). Idioms were embedded in short stories: in Experiment 1 only the idiomatic interpretation was contextually appropriate, in Experiment 2 a literal reading of the string was also plausible in the context. A multiple-choice task was used in both experiments: children were asked to choose one answer among three corresponding to: (a) the idiomatic meaning; (b) the literal meaning; and (c) an interpretation contextually appropriate but not connected with the idiomatic or literal meaning of the idiom string. The results of both experiments showed that the ability to understand a text indeed predicted children's understanding of idioms in context. To verify whether possible improvements in children's comprehension skills might produce an increase in figurative language understanding, Experiment 3 was carried out. A group of poor comprehenders who participated in Experiments 1 and 2 was tested eight months later. The results of Experiment 3 showed that children whose general comprehension skills improved their performance on an idiom comprehension test.     

Level of processing and age affect involuntary conceptual priming of weak but not strong associates

Memory for weak and strong semantic associates was compared in intentional associate-cued-recall and incidental free-association tests. This design yielded four conditions (weak/intentional, strong/intentional, weak/incidental, and strong/ incidental) on which younger and older adults were compared. Level of processing (LOP) and age effects occurred for the weak/intentional, strong/intentional, and weak/incidental conditions, but not for the strong/incidental condition. Because participants could not distinguish weak from strong associates during the memory tests, these results suggest that free-association priming was involuntary and was not contaminated by voluntary retrieval strategies. Instead, they suggest that encoding deficits related to shallower LOP and older age reduce involuntary free-association priming mainly for associates without cohesive preexperimental representations.     

Loneliness and depression in middle and late childhood: the relationship to attachment and parental styles

In this study, the author analyzed the relationship between (a) parenting and attachment and (b) self-competence, loneliness, and depression in children aged 8-12 years. The author administered (a) the Argentine Scale of Perception of the Relationships with Parents (M. C. Richaud de Minzi, 2004), (b) the Kerns' Security Scale (K. A. Kerns, L. Klepac, & A. K. Cole, 1996; M. C. Richaud de Minzi, C. Sacchi, & J. E. Moreno, 2001, Argentine adaptation), (c) the Self-Perception Profile for Children (S. Harter, 1985; M. C. Richaud de Minzi et al.), (d) the Dimensions of Depression Profile for Children and Adolescents (S. Harter & M. Nowakowski, 1987), and (e) the Louvain Loneliness Scale for Children and Adolescents (A. Marcoen, L. Goossens, & P. Caes, 1987; M. C. Richaud de Minzi et al.) to 1,019 children (8-12 years of age, 483 boys, 536 girls). Results indicated that attachment and parent-child relationship styles were differentiated constructs. Parents' acceptance promoted secure attachment and positive outcomes in children. Moreover, fathers' lack of interest had a marked negative effect. The author found differences in the perceptions and influences of fathers and mothers, which follow the cultural patterns of gender attribution.     

Preschoolers' current desires warp their choices for the future

We introduce a new paradigm to assess how children's choices for the future are influenced by their current desires. Forty-eight 3-, 4-, and 5-year-olds were assigned to one of four conditions. In two of these conditions (intervention), we manipulated children's current state of thirst by allowing them to eat pretzels. In the remaining two conditions (baseline), we did not give them pretzels. The children were then asked to choose between water and pretzels. In one intervention and one baseline condition, they chose what they would like "now," whereas in the other intervention and baseline conditions, they chose what they would like "tomorrow." Results revealed that, despite children's overwhelming desire for pretzels in the baseline conditions, children in both intervention conditions chose water. The data support the notion that children's current state influences not only their choices for the present, but also their choices for the future. We discuss this finding in terms of both cognitive-developmental and adult social-cognitive theory.     

A comparison of health behaviours in lonely and non-lonely populations

Loneliness can be defined as perceived social isolation and appears to be a relatively common experience in adults. It carries a significant health risk and has been associated with heart disease, depression and poor recovery after coronary heart surgery. The mechanisms that link loneliness and morbidity are unclear but one of the mechanisms may be through poor health beliefs and behaviours. The aims of this cross-sectional survey of 1289 adults were to investigate differences in health behaviours (smoking, overweight, BMI, sedentary, attitudes towards physical activity) in lonely and non-lonely groups. Lonely individuals were more likely to be smokers and more likely to be overweight - obese. The lonely group had higher body mass index scores controlling for age, annual income, gender, employment and marital status. Logistic regression revealed no differences in sedentary lifestyles. Lonely individuals were significantly less likely to believe it was desirable for them to lose weight by walking for recreation, leisure or transportation. The findings provide support for an association between health behaviours, loneliness and excess morbidity reported in previous studies.     

Detecting emotional faces and features in a visual search paradigm: are faces special?

In 2 experiments, participants were presented schematic faces with emotional expressions (threatening, friendly) in a neutral-faces context or neutral expressions in an emotional-faces context. These conditions were compared with detection performance in displays containing key features of emotional faces not forming the perceptual gestalt of a face. Supporting the notion of a threat detection advantage, Experiment 1 found that threatening faces were faster detected than friendly faces, whereas no difference emerged between the corresponding feature conditions. Experiment 2 increased task difficulty with a backward masking procedure and found corresponding results. In neither of the studies was the threat detection advantage associated with reduced accuracy. However, features were, in general, detected faster than faces when task difficulty was high.     

Aphasic naming in Spanish: predictors and errors

Sixteen Spanish aphasic patients named drawings of objects on three occasions. Multiple regression analyses were carried out on the naming accuracy scores. For the patient group as a whole, naming was affected by visual complexity, object familiarity, age of acquisition, and word frequency. The combination of variables predicted naming accuracy in 15 of the 16 individual patients. Age of acquisition, word frequency, and object familiarity predicted performance in the greatest number of patients, while visual complexity, imageability, animacy, and length all affected performance in at least two patients. High proportions of semantic and phonological errors to particular objects were associated with objects having early learned names while high proportions of no-response errors were associated with low familiarity and low visual complexity. It is suggested that visual complexity and object familiarity affect the ease of object recognition while word frequency affects name retrieval. Age of acquisition may affect both stages, accounting for its influence in patients with a range of different patterns of disorder.     

Virtual reality in the treatment of spider phobia: a controlled study

This study explored whether virtual reality (VR) exposure therapy was effective in the treatment of spider phobia. We compared a treatment condition vs. a waiting list condition in a between group design with 23 participants. Participants in the VR treatment group received an average of four one-hour exposure therapy sessions. VR exposure was effective in treating spider phobia compared to a control condition as measured with a Fear of Spiders questionnaire, a Behavioural Avoidance Test (BAT), and severity ratings made by the clinician and an independent assessor. Eighty-three percent of patients in the VR treatment group showed clinically significant improvement compared with 0% in the waiting list group, and no patients dropped out. This study shows that VR exposure can be effective in the treatment of phobias.     

Level of processing and the process-dissociation procedure: elusiveness of null effects on estimates of automatic retrieval

We describe two experiments that used the process-dissociation procedure to investigate the effects of level of processing on estimates of controlled and automatic retrieval processes in word-stem completion tasks. Despite our best endeavours, we found the null effect of level of processing on estimates of automatic retrieval reported by Toth, Reingold, and Jacoby (1994) elusive. Estimates of automatic retrieval were not independent of level of processing but inversely related to it. In part, the reason was that, following deeper levels of processing, instructions to exclude recollected words led to floor effects. But the inverse relationship persisted even when floor effects were avoided. Only participants who were not given strict instructions in the exclusion task-and who also qualified as lax responders based on answers in a structured post-test interview-showed no effect of level of processing on estimates of automatic retrieval. This null effect apparently occurred because these participants failed to exclude words that they in fact recollected from the study list. This finding violates the critical assumption that in this task participants exclude recollected words. The results are therefore paradoxical. Successful replication of the null effect occurred only under conditions that preclude the very use of the procedure. This paradox has important implications for views on how consciousness should be conceived in relation to memory.     

Motivation influences the underestimation of cumulative risk

Past research has shown that people typically underestimate the cumulative risk of events. This effect has mainly been interpreted as resulting from the use of cognitive heuristics and judgment strategies, such as availability or anchoring and adjustment. The authors suggest that motivational processes can be an additional force in the generation of cumulative risk estimates. Using an experimental design, Study 1 shows that people underestimate the cumulative risk of infection with sexually transmitted diseases of appealing prospective sexual partners by using risk-irrelevant information for their judgment. Using a correlational design, Study 2 demonstrates that people underestimate the cumulative risk of being infected with a sexually transmitted disease and that commitment to the present partner is directly related to a low cumulative risk estimate as well as indirectly through its effect on the perceived risk of the present partner. Together, the two studies demonstrate that motivation influences the underestimation of cumulative risk.
