If it is easy to remember,then it is not secure: Metacognitive beliefs affect password selection

In this research, we applied current theories of metacognition to study computer security and tested the idea that users' password selection is affected by the metacognitive belief that if a password is memorable, then it is not secure. In two experiments, different types of eight‐character passwords and longer, more secure sentences were presented. Participants rated perceived memorability and perceived security of the passwords and indicated whether they would use them in a critical and in a noncritical service. The results confirmed the belief. Sentences that are in fact highly secure and perceived as highly memorable were also perceived as weak passwords. The belief strongly affected password selection for critical services, but it had no effect on noncritical services. In sum, long sentences are a particularly interesting type of password because they meet both security and memorability criteria, but their use is limited by a false belief.     

Algebra and the adolescent brain

New fMRI evidence suggests that adolescents could be at an advantage for learning algebra compared with adults. Qin and colleagues present findings indicating that after several days of practice adolescents rely on prefrontal regions to support the retrieval of algebraic rules to solve equations, as do adults. Unlike adults, however, after practice adolescents decrease their reliance on parietal regions, which assist in the transformation of the equations, suggesting an enhanced ability for learning algebra. These findings are discussed with regard to adolescent brain maturation.     

Suicide attempts among adolescent Mexican American students enrolled in special education classes

Suicide is the second leading cause of death among school-aged students between the ages of 15 and 19. There is an increasing frequency of suicide and other self-destructive behaviors among Mexican American youth and students in special education classrooms for emotional and behavioral disabilities. Recognizing Mexican American youth in special education classes as a separate risk group, this study (a) identifies factors that contribute to suicide, (b) reviews the signs and characteristics associated with these factors, (c) interviews Mexican American students in special education who have either exhibited various characteristics of suicidal thoughts and/or have attempted suicide, (d) explores effective prevention programs, and (e) provides suggestions for school personnel. Interviews with five adolescent Mexican American special education students support previous research findings that depression, substance abuse, social and interpersonal conflict, family distress, and school stress are primary characteristics related to suicidal minority youth.     

Inhibitory Control and Working Memory in Post-Institutionalized Children

Inhibitory control and working memory were examined in post-institutionalized (PI) children adopted into United States families from Russian institutions. The PI sample originated from institutions that were less severely depriving than those represented in previous studies and approximated the level of psychosocial deprivation, which is characterized by adequate physical resources but a lack of consistent and responsive caregiving. PI children (N?=?75; 29 male) ranged in age from 8–17 years (M?=?12.97; SD?=?3.03) and were grouped according to whether they were adopted after 14 months or before 9 months. A non-adopted comparison group (N?=?133; 65 male) ranged in age from 8–17 years (M?=?12.26; SD?=?2.75). PI children adopted after 14 months of age displayed poorer performance on the stop-signal and spatial span tasks relative to PI children adopted before 9 months of age after controlling for age at assessment. The two PI groups did not differ in their performance on a spatial self-ordered search task. Older-adopted PI children also showed poorer spatial span task performance compared to non-adopted children, but younger-adopted PI children did not. Task performance was significantly associated with parent-rated hyperactive-impulsive behavior in everyday contexts. These findings suggest that exposure to prolonged early institutional deprivation may be linked with inhibitory control and working memory difficulties years after adoption.     

Maternal Mind-Mindedness and Children’s Behavioral Difficulties: Mitigating the Impact of Low Socioeconomic Status

Relations between mothers’ tendency to comment appropriately on their 8-month-olds’ internal states (mind-mindedness) and children’s behavioral difficulties (Strengths and Difficulties Questionnaire) at ages 44 and 61 months were investigated in a socially diverse sample (N?=?171, 88 boys). Controlling for maternal depressive symptoms, perceived social support, sensitivity, child language ability, and child gender, maternal mind-mindedness was negatively related to children’s externalizing and internalizing behaviors specifically in low socioeconomic status (SES) families. Furthermore, behavioral difficulties at age 44 months mediated the relation between maternal mind-mindedness and behavioral difficulties at age 61 months, but only for low SES families. These findings are discussed with reference to possible ways in which mind-mindedness could inform interventions targeted at at-risk groups.     

What Does it Mean to Notice my Students’ Ideas in Science Today?: An Investigation of Elementary Teachers’ Practice of Noticing their Students’ Thinking in Science

Abstract

Efforts toward improving K-12 science education emphasize teachers noticing students’ thinking as they engage in disciplinary practices and reasoning. This noticing requires specialized teacher knowledge and skills as it involves attending to students’ ideas, as well as making sense of and responding to those ideas so that the disciplinary substance in them is recognized, made explicit, and supported. This study investigates three elementary teachers’ in-the-moment noticing of students’ ideas while teaching science and their thinking about what it means to engage in this teaching practice. Results indicate that teachers notice many different kinds of student science ideas, and also that teachers have different ways of thinking about which student ideas are substantive during a science lesson. This research contributes to our theoretical understanding of the nature of teacher noticing in science. Noticing students’ science ideas involves not only the presence of ideas and the ability to notice them, but also a teacher’s understanding of this teaching practice in the moment.     

Monitoring the source monitoring

The hypothesis that the retrieval of correct source memory cues, those leading to a correct source attribution, increases confidence, whereas the retrieval of incorrect source memory cues, those leading to a source misattribution, decreases confidence was tested. Four predictions were derived from this hypothesis: (1) confidence should be higher for correct than incorrect source attribution except; (2) when no source cues are retrieved; (3) only the source misattributions inferred from the retrieval of incorrect source cues will be rated with low confidence; and (4) the number of source cues retrieved, either correct or incorrect, will affect the confidence in the source attributions. To test these predictions, participants read two narratives from two witnesses to a bank robbery, a customer and a teller. Then, participants completed a source monitoring test with four alternatives, customer, teller, both, or neither, and rated their confidence in their source attribution. Results supported the first three predictions, but they also suggested that the number of correct source monitoring cues retrieved did not play a role in the monitoring of the accuracy of the source attributions. Attributions made from the recovery of incorrect source cues could be tagged as dubious or uncertain, thus leading to lowered confidence irrespective of the number of incorrect source cues or whether another correct source cue was also recovered. This research has potential applications for eyewitness memory because it shows that confidence can be an indicator of the accuracy of a source attribution.     

Deconfounding the Effects of Local Element Spatial Heterogeneity and Sparsity on Processing Dominance

Black and White American college students were compared to determine how daily hassles, coping strategies, and social support related to depression. Although the mean intensity of hassles did not differ, Black students reported a higher frequency of hassles. Cumulative severity of hassles, defined in terms of both intensity and frequency was therefore higher for Black students. White students perceived more support from friends than from family, but the opposite held for Black students. Mean scores on type of coping (active problem solving, seeking social support, or avoidance) were similar, as were the reported levels of depression. Hierarchical multiple regression showed that the severity of hassles was directly related to depression for both groups. Race did not interact with any index of social support, except perceived family support, which was related to lower depression among Black students. There was no support for the notion that social support serves as a buffer against depression.     

Effects of Interest,Thematic Congruence,and Typicality on Memory for Television,Radio, and Press Advertisements of New Products

Little is known about how the content of advertisements is remembered. We studied how product interest, thematic congruence between advertisement and programme, and the typicality of the elements of an advertisement affect memory for new product ads in television, radio, and printed media. Participants were exposed to a single type of media with two embedded ads. After a filler task, they completed a true/false recognition task. In television and radio, accuracy was higher for the interesting product ads. In three experiments, we found no effect of thematic congruence, and the standard effect of typicality. In printed media, where participants are free to read the ads or not, the differences in hits and false alarms in typicality were due to a change in the response criterion and not to an effect on memory. We conclude that different results can be obtained depending on the exposure to different media. Copyright © 2015 John Wiley & Sons, Ltd.     

The relationship between spirituality and depressive symptom severity,psychosocial functioning impairment,and quality of life: examining the impact of age,gender, and ethnic differences

Research has documented the contribution of spirituality on overall health and mental health among college students. However, very few studies have explored the impact of cultural and ethnic differences on the effect of spirituality on mental health outcomes in this population. The aims of this study were to examine the relationships among spirituality, depressive symptom severity, psychosocial functioning impairment, and quality of life in a large multi-ethnic sample of college students and explore the impact of age, gender, and ethnicity on these relationships. The sample consisted of Latino, African-American, Caucasian, and Caribbean/West Indian college students. Findings indicated that spirituality, believing in God's presence, age, gender, and ethnicity were significantly related to depressive symptoms. These factors were also associated with impairment in psychosocial functioning and quality of life related to depression.
