Summary: My comment is basically restricted to the situation in which less-able students find themselves and refers only to literature in German. From this point of view I am basically able to confirm Marsh's results. It must, however, be said that with less-able pupils the opposite effect can be found: Levels of self-esteem in these pupils are raised, at least temporarily, by separate instruction, academic performance however drops; combined instruction, on the other hand, leads to improved academic performance, while levels of self-esteem drop. Apparently, the positive self-image of less-able pupils who receive separate instruction does not bring about the potential enhancement of academic performance one might expect from high-ability pupils receiving separate instruction. To resolve the dilemma, it is proposed that individual progress in learning be accentuated, and that comparisons with others be dispensed with. This fosters a self-image that can in equal measure be realistic and optimistic.

The Difference

Abstract. Two experiments tested the hypothesis that self-evaluation can serve as a source of interpersonal attitudes. In the first study, self-evaluation was manipulated by means of false feedback. A subsequent learning phase demonstrated that the co-occurrence of the self with another individual influenced the evaluation of this previously neutral target. Whereas evaluative self-target similarity increased under conditions of negative self-evaluation, an opposite effect emerged in the positive self-evaluation group. A second study replicated these findings and showed that the difference between positive and negative self-evaluation conditions disappeared when a load manipulation was applied. The implications of self-evaluation for attitude formation processes are discussed.

Internal Knowledge

People often filter their experience of new events through knowledge they already have, e.g., encoding new events by relying on prototypical event “scripts” at the expense of actual details. Previous research suggests that positive affect often increases this tendency. Three studies assessed whether awe—an emotion elicited by perceived vastness, and thought to promote cognitive accommodation—has the opposite effect, reducing rather than increasing reliance on event scripts. True/false questions on details of a short story about a romantic dinner were used to determine whether awe (1) reduces the tendency to impute script-consistent but false details into memory, and/or (2) promotes memory of unexpected details. Across studies we consistently found support for the first effect; evidence for the second was less consistent. Effects were partially mediated by subjective awe, and independent of other aspects of subjective affect. Results suggest that awe reduces reliance on internal knowledge in processing new events.©American Psychological Association, 2017.

It has been found that [VO(acac)2] and [Co(acac)3] increase the rate of t-BuOOH photolysis, whereas [Fe(acac)3] has the opposite effect. Redox changes of the catalytically active [VO(acac)2] were followed using the EPR technique. An EPR signal from a free radical intermediate of photochemical decomposition of t-BuOOH was recorded, and the concentration of the intermediate was monitored during the reaction.

Segmental Differentiation

Mutations of the Drosophila homeotic proboscipedia gene (pb; the Hox-A2/B2 homologue) provoke dose-sensitive defects. These were used to search for dose-sensitive dominant modifiers of pb function. Two identified interacting genes were the proto-oncogene Ras1 and its functional antagonist Gap1, prominent intermediaries in known signal transduction pathways. Ras1+ is a positive modifier of pb activity both in normal and ectopic cell contexts, while the Ras1-antagonist Gap1 has an opposite effect. A general role for Ras1 in homeotic function is likely, since Ras1+ activity also modulates functions of the homeotic loci Sex combs reduced and Ultrabithorax. Our data suggest that the modulation occurs by a mechanism independent of transcriptional control of the homeotic loci themselves, or of the Ras1/Gap1 genes. Taken together our data support a role for Ras1-mediated cell signaling in the homeotic control of segmental differentiation.

Light Responses

The neuronal generators of the b- and d-waves of the electroretinogram (ERG) were investigated in the tiger salamander retina to determine if amacrine and ganglion cells contribute to this field potential. Several agents were used that affect third-order neurons, such as tetrodotoxin, baclofen, and NMDA agonists and antagonists. Baclofen, an agent that enhances light responses in third-order neurons, increased the d-wave and reduced the b-wave. In contrast, agents that decrease light responses in third-order neurons had the opposite effect of enhancing the b-wave and depressing the d-wave. The effect on the d-wave was particularly pronounced. The results indicate that third-order neuronal activity influences b- and d-waves of the ERG. The opposing actions suggest that the b-wave to d-wave ratio might serve as an measure of ganglion cell function.

Fixed Amount

9 soldiers were required to perform a fixed amount of work on a bicycle ergometer during each of 18 sessions. Ss were allowed to determine their own schedules of work and rest. Ss breathed air during the first 9 sessions (Training). During the second 9 sessions (Experimental) Ss breathed either 21, 14, or 12% O2. Results indicated that Ss paced themselves by stopping rather than changing their rate of pedaling. Training reduced the number of stops per session, while hypoxia had the opposite effect.
