Créativité verbale et valence émotionnelle : « Je deviens plus créatif quand je vois un mot positif ! »

IntroductionThe modulating effect of emotion on creativity is one of the most current topics in cognitive research. Emotion, and particularly positive emotion, is supposed to be conducive of creativity and to enhance the processes of creative thinking.ObjectiveThis work aimed to study the modulating effect of emotional valence of the task material (words-stimuli) as well as the emotional valence of the task instructions on verbal creativity performance.MethodAn experiment was conducted on a set of 27 stimuli-words and six instructions-phrases selected on the basis of pretest valence ratings. The valence of the stimuli-words (negative, neutral and positive) was crossed with the valence of the instructions-phrases (negative, neutral and positive) in a 3 × 3 factorial design. However, only five experimental conditions were considered relevant and used in the Experiment. Three components of verbal creativity identified in the literature were measured: fluidity, flexibility and originality.ResultsResults showed that positive instructions and words increased verbal creativity, especially the originality of the responses, which is considered as a basic component of creativity. Conversely, negative valence had an inhibitory and obstructive effect on verbal creativity.ConclusionThis study supports previous research showing the existence of a significant influence of emotional valence of words on cognitive functioning, and adds to the very little (or absent) research on the modulating effect of the valence of instructions and on the relationship between verbal creativity and emotional valence, a relationship that can be fostered in education.     

Avoidant instructions induce ironic and overcompensatory movement errors differently between and within individuals

Giving avoidant instructions can ironically result in the forbidden act being carried out, especially when the person is anxious or cognitive loaded. However, the consistency with which individuals make ironic errors across conditions remains unexamined. Forty participants were instructed to avoid moving a cursor above, below, left, and right when tracing an invisible line connecting two points while rehearsing seven-digit numbers on half of trials. Results showed that, without cognitive load, 26 participants made consistent overcompensatory movements, 10 made consistent ironic errors, and 4 showed no distinct error bias, with levels of somatic anxiety predicting this pattern. However, 21 (52.5%) participants changed their error tendency when cognitive loaded, indicating that movement effects of avoidant instruction were not experienced as general phenomena but rather differed between and within individuals. Overcompensatory errors made by participants grouped as overcompensatory performers under low load were significantly larger than the ironic errors made by participants grouped as ironic performers under low load, yet, paradoxically, ironic performers reported higher state and trait anxiety. Overall, results demonstrate a clear experimenter bias inherent in the use of avoidant instructions to direct participants' motor control.     

Visual context does not promote concurrent sequence learning

Concurrent sequence learning (CSL) of two or more sequences refers to the concurrent maintenance, in memory, of the two or more sequence representations. Research using the serial reaction time task has established that CSL is possible when the different sequences involve different dimensions (e.g., visuospatial locations versus manual keypresses). Recently some studies have suggested that visual context can promote CSL if the different sequences are embedded in different visual contexts. The results of these studies have been difficult to interpret because of various limitations. Addressing the limitations, the current study suggests that visual context does not promote CSL and that CSL may not be possible when the different sequences involve the same elements (i.e., the same target locations, response keys and effectors).     

The Prevention of Reading Difficulties

The purpose of this article is to provide practical advice about methods to prevent reading failure that is grounded in the new knowledge we have acquired about reading and learning to read over the past 2 decades. Recent research on reading is used to establish a set of facts about reading and reading growth that is relevant to establishing instructional objectives and methods for the prevention of reading difficulties. Within the context of our current understanding of the reasons many children find it difficult to learn to read, the article also identifies the instructional conditions that need to be in place to prevent the development of reading difficulties in all but a very small proportion of children. The article concludes with a discussion of issues and procedures for the early identification of children who are likely to experience difficulties learning to read.     

Episodic memory and the hippocampus: it's about time

Several recent studies have sought to develop animal models of episodic memory, the capacity to recollect unique personal experiences. However, these studies have not yet provided unambiguous evidence that this capacity is based on recollection of the learning episodes. A recent study that examined memory for the ordering of events within unique experiences, and demonstrated a critical and selective role for the hippocampus, suggests a new and promising model for neurobiological analyses of episodic memory.

The Instructional Characteristics of Inclusive Classes for Elementary Students with Severe Disabilities: An Exploratory Study

This exploratory study examined several instructional characteristics of elementary classrooms serving students with severe disabilities including the individuals who provided instruction to students, the instructional behaviors of these teachers, and grouping structures. The analysis focused on the impact of these variables on the academic responding of students and the extent to which they were the exclusive target of instruction by the various teachers. Observation data were collected on six students with severe disabilities participating in general elementary classrooms for reading or math, and at least one other subject area. The academic responding of students was similar across general education teachers, special education teachers, paraprofessionals, and peers; and the instructional behaviors of each of these groups of instructors was similar. Students had higher rates of academic responding during one-on-one and small group instruction, but they also were engaged in instructional tasks during whole class instruction. Finally, academic responding was positively associated with instruction focused on the student, one-on-one instruction, and instructional interactions with teachers. Academic responding was negatively correlated with whole class instruction and instructional behaviors that were not directed at the student.     

Implicit sequence learning in ring‐tailed lemurs (Lemur catta)

Implicit learning involves picking up information from the environment without explicit instruction or conscious awareness of the learning process. In nonhuman animals, conscious awareness is impossible to assess, so we define implicit learning as occurring when animals acquire information beyond what is required for successful task performance. While implicit learning has been documented in some nonhuman species, it has not been explored in prosimian primates. Here we ask whether ring‐tailed lemurs (Lemur catta) learn sequential information implicitly. We tested lemurs in a modified version of the serial reaction time task on a touch screen computer. Lemurs were required to respond to any picture within a 2 × 2 grid of pictures immediately after its surrounding border flickered. Over 20 training sessions, both the locations and the identities of the images remained constant and response times gradually decreased. Subsequently, the locations and/or the identities of the images were disrupted. Response times indicated that the lemurs had learned the physical location sequence required in original training but did not learn the identity of the images. Our results reveal that ring‐tailed lemurs can implicitly learn spatial sequences, and raise questions about which scenarios and evolutionary pressures give rise to perceptual versus motor‐implicit sequence learning.     

Effects of a Peer-Delivered Corrective Reading Program

The effects of a peer-delivered Corrective Reading program (CRP) (Engelmann, Hanner, & Johnson, 1989) with repeated reading on the reading performance of at-risk high school students were examined. High school peer instructors and students in need of reading remediation were randomly assigned to dyads or triads. Peer instructors presented the CRP, conducted repeated reading trials, and took rate and accuracy measures. Pre to post test data were collected on vocabulary and comprehension subtests of the Gates–MacGinitie Reading Tests, oral reading fluency (words read per minute) and accuracy, number of repeated readings on initial and final lessons, and lessons completed. Results indicated that students' performance on the standardized reading assessment increased as did their oral reading fluency. In general, the number of repeated readings decreased from the initial lesson to the final lesson. Implications for further research are discussed.
