Resumen

En el presente trabajo de investigación nos interesamos por dar a conocer las características psicométricas y estructurales de una nueva escala de evaluación de estrategias de aprendizaje escolar, así como también por el tipo de relación que mantiene este constructo con otras variables o correlatos importantes en el funcionamiento cognitivo como son los procesos de atribución, el autoconcepto y la motivación académica La muestra de sujetos, en base a la cual se realiza el estudio, está compuesta por 371 alumnos/as de 5°, 6°, 7° y 8° de E.G.B., pertenecientes a colegios públicos de la zona central del Principado de Asturias, de los cuales 192 son chicos y 179 son chicas. Su nivel socioeconómico es medio y pertenecen a una zona industrial. Los resultados obtenidos indican que (a) la escala LASSI es moderadamente fiable y con una estructura factorial que pudiera variar con la edad de los sujetos, (b) que existen diferencias entre niños y niñas en algunas de las dimensiones estratégicas así como también respecto a la edad de los mismos y (c) las estrategias de aprendizaje se encuentran notablemente relacionadas con los procesos atribucionales, el autoconcepto, las metas de estudio y el rendimiento de los alumnos. En el último punto del trabajo, en primer lugar, advertimos de la naturaleza exploratoria y provisionalidad de los datos obtenidos así como de la neceidad de la realización de otras investigaciones con el fin de disipar ciertas discrepancias y, en segundo lugar, interpretamos los resultados de nuestro trabajo contextualiz ándolos dentro de las actuales teorías metacognitiv as de la instrucción.  相似文献

In long‐term memory (LTM) emotional content may both enhance and impair memory, however, disagreement remains whether emotional content exerts different effects on the ability to maintain and manipulate information over short intervals. Using a working‐memory (WM) recognition task requiring the monitoring of faces displaying facial expressions of emotion, participants judged each face as identical (target) or not (non‐target) to that presented 2 trials back (2‐back). Negative expression was better and faster recognised, illustrated by higher target discriminability and target detection. Positive and negative expressions also induced a more liberal detection bias compared with neutral. Taking the preceding item into account, additional accuracy impairment (negative preceding negative target) and enhancement effects (negative or positive preceding neutral target) appeared. This illustrates a differential modulation of WM based on the affective tone of the target (mirroring LTM enhancement‐ and recognition bias effects), and of the preceding item (enhanced and impaired target detection).  相似文献

Several neurological patient populations, including traumatic brain injury (TBI), appear to produce an abnormally ‘utilitarian’ pattern of judgements to moral dilemmas; they tend to make judgements that maximize the welfare of the majority, rather than deontological judgements based on the following of moral rules (e.g., do not harm others). However, this patient research has always used extreme dilemmas with highly valued moral rules (e.g., do not kill). Data from healthy participants, however, suggest that when a wider range of dilemmas are employed, involving less valued moral rules (e.g., do not lie), moral judgements demonstrate sensitivity to the psychological intuitiveness of the judgements, rather than their deontological or utilitarian content (Kahane et al., Social Cognitive and Affective Neuroscience, 7, 2011, 393). We sought the moral judgements of 30 TBI participants and 30 controls on moral dilemmas where content (utilitarian/deontological) and intuition (intuitive/counter‐intuitive) were measured concurrently. Overall TBI participants made utilitarian judgements in equal proportions to controls; disproportionately favouring utilitarian judgements only when they were counter‐intuitive, and deontological judgements only when they were counter‐intuitive. These results speak against the view that TBI causes a specific utilitarian bias, suggesting instead that moral intuition is broadly disrupted following TBI.  相似文献

The current study examined the influence of observing another's lie‐ or truth‐telling – and its consequences – on children's own honesty about a transgression. Children (N = 224, 5–8 years of age) observed an experimenter (E) tell the truth or lie about a minor transgression in one of five conditions: (a) Truth‐Positive Outcome – E told the truth with a positive outcome; (b) Truth‐Negative Outcome – E told the truth with a negative outcome; (c) Lie‐Positive Outcome – E lied with a positive outcome; (d) Lie‐Negative Outcome – E lied with a negative outcome; (e) Control – E did not tell a lie or tell the truth. Later, to examine children's truth‐ or lie‐telling behavior, children participated in a temptation resistance paradigm where they were told not to peek at a trivia question answer. They either peeked or not, and subsequently lied or told the truth about that behavior. Additionally, children were asked to give moral evaluations of different truth‐ and lie‐telling vignettes. Overall, 85% of children lied. Children were less likely to lie about their own transgression in the TRP when they had previously witnessed the experimenter tell the truth with a positive outcome or tell a lie with a negative outcome.  相似文献

First language (L1) attrition in adulthood offers new insight on neuroplasticity and the role of language experience in shaping neurocognitive responses to language. Attriters are multilinguals for whom advancing L2 proficiency comes at the cost of the L1, as they experience a shift in exposure and dominance (e.g., due to immigration). To date, the neurocognitive mechanisms underlying L1 attrition are largely unexplored. Using event‐related potentials (ERPs), we examined L1‐Italian grammatical processing in 24 attriters and 30 Italian native‐controls. We assessed whether (a) attriters differed from non‐attriting native speakers in their online detection and re‐analysis/repair of number agreement violations, and whether (b) differences in processing were modulated by L1‐proficiency. To test both local and non‐local agreement violations, we manipulated agreement between three inflected constituents and examined ERP responses on two of these (subject, verb , modifier ). Our findings revealed group differences in amplitude, scalp distribution, and duration of LAN/N400 + P600 effects. We discuss these differences as reflecting influence of attriters’ L2‐English, as well as shallower online sentence repair processes than in non‐attriting native speakers. ERP responses were also predicted by L1‐Italian proficiency scores, with smaller N400/P600 amplitudes in lower proficiency individuals. Proficiency only modulated P600 amplitude between 650 and 900 ms, whereas the late P600 (beyond 900 ms) depended on group membership and amount of L1 exposure within attriters. Our study is the first to show qualitative and quantitative differences in ERP responses in attriters compared to non‐attriting native speakers. Our results also emphasize that proficiency predicts language processing profiles, even in native‐speakers, and that the P600 should not be considered a monolithic component.  相似文献

Resumen

Los comportamientos de engaño suelen relacionarse con la intencionalidad y la conciencia, aunque desde una perspectiva evolutiva amplia puede apreciarse que el engaño es una estrategia evolutiva bastante antigua. En este artículo se discutirá en qué medida los engaños que producen los seres humanos y algunos otros primates pueden entenderse como el producto de una competencia básica para atribuir mente a los demás y no a uno mismo. El criterio más aceptado para determinar si un organismo posee tal capacidad mentalista es que demuestre la comprensión de las creencias falsas. Las situaciones de engaño en las que se crean deliberadamente creencias falsas en otros para conseguir beneficios cumplen teóricamente bien los criterios de mentalismo que los humanos alcanzan hacia la edad de cuatro años y medio. En otros primates no se ha demostrado experimentalmente con claridad la comprensión de las creencias falsas. Sin embargo, si atendemos a los datos de observación naturalista vemos numerosos comportamientos de engaño tanto en algunos primates no humanos como en niños menores de cuatro años. ¿Son estos engaños el producto de una teoría de la mente? ¿De una capacidad mentalista previa? ¿Quéotros estados mentale estarían implicados? Tras una revisión crítica de los trabajos que nos proporcionan estos datos, se discutirá el papel de la manipulaión y detección de intenciones como un proceso anterior a la manipulación de creencias falsas y las implicaciones que esta postura tiene para la consideración evolutiva de la capacidad mental.  相似文献

Three basic findings have emerged from research on maternal depressive symptoms and offspring hypothalamic–pituitary–adrenal functioning: (a) Mothers’ depressive symptoms are positively associated with their offsprings’ cortisol stress response, (b) numerous individual and interpersonal maternal characteristics moderate this association, and (c) maternal and infant cortisol levels are highly correlated. In combination, these findings have suggested that maternal cortisol levels may moderate the relation between maternal depressive symptoms and infant cortisol responsivity; the current study assessed this hypothesis. Participants were 297 mother–infant dyads who were recruited from the community. Maternal depressive symptoms were assessed via self‐report. Dyads participated in two differentially stressful infant challenges when infants were 16 and 17 months old. Mother and infant salivary cortisol was collected before and after challenges. Results indicate that maternal cortisol levels moderated associations between maternal depressive symptoms and infant cortisol levels across both challenges. Infants showed higher cortisol levels if their mothers had both higher depressive symptoms and higher cortisol levels, as compared to infants of mothers with higher depressive symptoms and lower cortisol, and to infants of mothers with lower depressive symptoms and either higher or lower cortisol levels. We discuss findings in relation to environmental and biological factors that may contribute to the intergenerational transmission of depressive symptoms.  相似文献

Drawing on uncertainty‐identity theory (Hogg, 2012), we explore the effects of uncertainty concerning a specific social identity on group identification and attitudes toward subgroup integration and separation in South Koreans' nested identity context (N = 148). All variables were measured. Path analysis revealed, as predicted, that superordinate identity uncertainty weakened superordinate identification and subgroup identity uncertainty weakened subgroup identification. We also found that subgroup identity uncertainty strengthened superordinate identification. This effect was stronger for those who perceived their superordinate group prototype and subgroup prototype to be distinct and nonoverlapping. Furthermore, superordinate identity uncertainty decreased reunification intentions by weakening superordinate identification. Subgroup identity uncertainty increased reunification intentions by strengthening superordinate identification only for those who perceived their superordinate group prototype and subgroup prototype to be distinct and nonoverlapping. Implications for uncertainty identity theory and intergroup relations are discussed.  相似文献

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.  相似文献

Structural factors associated with public housing contribute to living environments that expose families to adverse life events that may in turn directly impact parenting and youth outcomes. However, despite the growth in research on fathers, research on families in public housing has practically excluded fathers and the role fathers play in the well‐being of their adolescents. Using a sample of 660 African American adolescents recruited from public housing, we examined the relationship between paternal caregivers’ (i.e., fathers’ and father figures’) parenting practices and adolescents’ depressive symptoms, attitudes toward deviance, and self‐efficacy. Using a latent profile analysis (LPA), we confirmed a four‐class model of paternal parenting practices ranging from high to low levels of monitoring and encouragement. Results from a one‐way ANOVA indicated that paternal caregivers with high (compared to moderate) levels of encouragement and monitoring were associated with youth who reported less depressive symptoms, higher levels of self‐efficacy, and less favorable attitudes toward deviance. Discriminant analysis results indicated that approximately half of the sample were correctly classified into two paternal caregiver classes. The findings provide evidence that some of these caregivers engage in parenting practices that support youths’ psychological functioning. More research is needed to determine what accounts for the variability in levels of paternal encouragement and supervision, including environmental influences, particularly for paternal caregivers exhibiting moderate‐to‐low levels of paternal encouragement and monitoring.  相似文献
