Imagen mental e intervalo de retención en el recuerdo de series

Resumen

En dos experimentos estudiamos la influencia de la capacidad de formar imágenes mentales, el tipo de imagen utilizada por los sujetos (no imagen, imagen normal e imagen rara), y el intervalo de retención, en el recuerdo serial de palabras. Se utilizaron dos muestras de estudiantes y se averiguó si en los experimentos obedecían o no las instrucciones dadas por el experimentador. Todos los sujetos que no las cumplieron, según la opinión de dos jueces, fueron rechazados. En el experimento 1 se analiza la influencia de estas variables en el aprendizaje serial de listas cortas (16 items) y, en el Experimento 2, se analiza la influencia en listas largas (28 items). Todas las variables influyeron de forma significativa en el recuerdo.     

Coming Out in Voices

This paper articulates the personal experiences of a woman with a physical disability who enters therapy to explore issues involving lesbian identity, health and illness, disability oppression and pride, and relationships. Written in the first person, the article uses anecdotes, poetry, and journal entries to chart the author's process of self-discovery. As a woman, a lesbian, and a person with a disability, the author frequently finds herself at odds with the culture around her. This creates conflicts between the author's real self, and the self she must present to others. She discusses how she had learned to "silence the voices" which were not useful in challenging the stereotypes, making others comfortable, or communicating with assistants. The author describes how therapy offered her the opportunity to unlearn the silence, value all of her voices, listen to herself, resolve her internal dilemmas, and develop a deeper sense of self.     

The role of articulatory suppression in immediate false recognition

False memory for critical lures has been widely documented in long-term memory using the Deese/Roediger-McDermott paradigm. Recent evidence suggests that false memory effects can also be found in short-term memory (STM), supporting models that assume a strong relationship between short-term and long-term memory processes. However, no study has examined the role of articulatory suppression on immediate false memory, even though phono-articulatory factors are critically involved in STM performance and are an intrinsic part of all STM accounts. The current study proposes a novel paradigm to assess false memory effects in a STM task under both silent and articulatory suppression conditions. Using immediate serial recognition, in which participants had to judge whether two successive mixed lists of six associated and non-associated words were matched, we examined true recognition of matching lists and false recognition of mismatching lists comprising a critical lure or unrelated distractor in two experiments. Results from both experiments indicated reduced true recognition of matching lists and greater false serial recognition of mismatching lists comprising a critical lure under articulatory suppression relative to silence. These findings provide further support for some current models of verbal short-term memory, which posit a strong relationship between short-term and long-term memory processes.     

The pigeon's discrimination of shape and location information

Two groups of pigeons (n = 4) were trained with 16 line drawings portraying a fixed shape and a variable shape. The four variable shapes (a wedge, a cone, a cylinder, and a handle) appeared to the left of, to the right of, above, or below the fixed shape (a cube). Group Shape (S) was required to discriminate the identity of the variable shape that was mated with the cube, whereas Group Location (L) was required to discriminate where the variable shape appeared relative to the cube. Three of the four pigeons in each group mastered their respective tasks. Later tests revealed that the two groups of pigeons had attended to different aspects of the shape pairs, even though the visual stimuli and general procedures they had been given were the same. Group S had attended to the identity of the variable shape and had ignored the identity and location of the cube, whereas Group L had attended to the configuration of the two shapes. The methods and stimuli could be useful in delineating the biological bases of shape and location perception.     

The Effective Treatment of Juveniles Who Sexually Offend: An Ethical Imperative

This article raises serious concerns regarding the widespread use of unproven interventions with juveniles who sexually offend and suggests innovative methods for addressing these concerns. Dominant interventions (i.e., cognitive-behavioral group treatments with an emphasis on relapse prevention) typically fail to address the multiple determinants of juvenile sexual offending and could result in iatrogenic outcomes. Methodologically sophisticated research studies (i.e., randomized clinical trials) are needed to examine the clinical and cost-effectiveness of cognitive-behavioral group interventions, especially those delivered in residential settings. The moral and ethical mandate for such research is evident when considering the alternative, in which clinicians and society are willing to live in ignorance regarding the etiology and treatment of juvenile sexual offending and to consign offending youths to the potential harm of untested interventions. Encouraging signs of a changing ethical climate include recent federal funding of a randomized clinical trial examining treatment effectiveness with sexually offending youths and the introduction of separate (i.e., developmentally informed) clinical and legal interventions for juvenile versus adult sexual offenders.     

Individualized Challenge Point Practice as a Method to Aid Motor Sequence Learning

We conducted two studies to investigate if and how: (1) the rate of skill acquisition was related to motor performance at retention of a serial RT task (Study 1); and (2) whether rate of skill acquisition and baseline performance could be used to design schedules of practice related to contextual interference (CI) to enhance motor learning (Study 2). In Study 1, a slower rate of skill acquisition of repeating sequences in practice was related to faster response times at retention. Based on performance in Study 1, three levels of individualized CI were created for Study 2. Compared to low and moderate levels of CI, the higher CI practice condition led to faster response times in retention. We conclude that an individualized ‘challenge point’, which generates high CI enhances motor learning by optimizing challenge.     

The Internal Consistency of Moral Reasoning: A Multitrait-Multimethod Assessment

The consistency of moral judgment across five dimensions (immanent justice, moral realism, retribution vs. restitution, efficacy of severe punishment, and communicable responsibility) from two basic, structural components of the cognitive-developmental approach was examined. The two components were (a) the more general concept of level and (b) the more specific concept of stage. Multitrait-multimethod analysis supported the compatibility between the two constructs. The methods differed in their degree of association between the five measured dimensions; the stage technique appeared to be more consistent than the level scale. Finally, comparisons between dimensions indicated that the notion of moral development seems to be multidimensional, vis-à-vis unidimensional, as originally implied by Piaget and later by Kohlberg.     

Differentiating sexual preference in men: Using dual task rapid serial visual presentation task

Cognition research suggests that allocating attention resources to evolutionarily relevant stimuli is facilitated suggesting that sexual stimuli interfere with human information processing. In a group of gay (n = 13) and straight men (n = 13) recruited in Finland, Germany and Italy, we investigated if and how sexually relevant visual stimuli affect information processing of both a target one (T1) and a subsequent target two (T2) in a dual target rapid serial visual presentation procedure. We hypothesized that: (1) due to the attentional blink (AB) phenomenon, the accuracy of reporting of T2 would decrease when following accurately identified sexually preferred T1 compared to accurately identified non‐sexually preferred T1; 2) due to the pop out effect, the accuracy of reporting of T1 and T2 would be relatively increased when T1 and T2 were sexually preferred by the participants compared to when they were not. Our findings did not support hypothesis 1 but supported hypothesis 2. We further found that the pop out effect had a good capacity to differentiate sexual preference between the groups of gay and straight men. We conclude that dual target rapid serial visual presentation can be used as an attention‐based measurement to differentiate sexual preference in men. Limitations and the applicability in the field of measuring sexual preference were discussed.
