Wicherts and Scholten criticized our study on statistical and psychometric grounds. We show that (i) using a continuous income variable, the interaction between income, and experimental manipulation remains reliable across our experiments; (ii) our results in the cognitive control task do not appear driven by ceiling effects; and (iii) our observed post-harvest improvement is robust to the presence of learning. 
Median Splits, Type II Errors, and False Positive Consumer Psychology: Don't Fight the Power
Considerable prior statistical work has criticized replacing a continuously measured variable in a general linear model with a dichotomy based on a median split of that variable. Iacobucci, Posovac,
Cognition for dinner Does financially impaired cognitive function affect healthy meal choice
Neglecting health consequences when establishing dietary habits can lead to poor health outcomes. Earlier research has argued that counterproductive behavioral outcomes may be caused by resource
The duality of poverty: a replication of Mani et al. (2013) in Colombia
Scarcity acts as a mental burden that disrupts how people process information and make decisions (Mullainathan and Shafir in Scarcity: Why having too little means so much. Macmillan, Basingstoke,
Testing Age Differences in the links between Recent Financial Difficulties and Cognitive Deficits: Longitudinal Evidence from the PATH Through Life Study.
New evidence is provided that financial difficulties in later life are potent stressors associated with occasion specific deficits in cognitive performance, with weak evidence of stronger associations in mid-life relative to other age groups.
Poverty and economic decision making: a review of scarcity theory
Poverty is associated with a wide range of counterproductive economic behaviors. Scarcity theory proposes that poverty itself induces a scarcity mindset, which subsequently forces the poor into
Toward a More Nuanced Understanding of the Statistical Properties of a Median Split
Abstract Some behavioral researchers occasionally wish to conduct a median split on a continuous variable and use the result in subsequent modeling to facilitate analytic ease and communication
Privacy for Burdened Minds
This research project has been trying to connect theories and findings from both the research on economic trade-offs and online privacy trade-offs. Within these fields it was found that monetary


Comment on “Poverty Impedes Cognitive Function”
A reanalysis without dichotomization of income fails to corroborate their findings and highlights spurious interactions between income and experimental manipulation due to ceiling effects caused by short and easy tests, suggesting that effects of financial worries are not limited to the poor.
Poverty Impedes Cognitive Function
It is suggested that poverty-related concerns consume mental resources, leaving less for other tasks, because poverty itself reduces cognitive capacity.
On Making the Right Choice: The Deliberation-Without-Attention Effect
The hypothesis that simple choices indeed produce better results after conscious thought, but that choices in complex matters should be left to unconscious thought was confirmed in four studies on consumer choice.
Recursive Processes in Self-Affirmation: Intervening to Close the Minority Achievement Gap
An intervention, a series of brief but structured writing assignments focusing students on a self-affirming value, reduced the racial achievement gap and treated students' self-perceptions showed long-term benefits.
Numeracy and Decision Making
Findings were consistent with highly numerate individuals being more likely to retrieve and use appropriate numerical principles, thus making themselves less susceptible to framing effects, and their affective responses were more precise.
Doing Better but Feeling Worse
This investigation compared the choice-making strategies of maximizers and satisficers, finding that maximizing tendencies, although positively correlated with objectively better decision outcomes, are also associated with more negative subjective evaluations of these decision outcomes.
A functional genetic variation of the 5-HT2a receptor affects human memory
A functional variation of a memory-related serotonin receptor in 349 healthy young volunteers is investigated, and it is found that 21% poorer memory performance in subjects with the rare variant is found.
Creating False Memories of Words With or Without Recognition of List Items: Evidence for Nonconscious Processes
Subjects exposed to lists of semantically related words falsely remember nonstudied words that are associated with the list items (e.g., Deese, 1959; Roediger & McDermott, 1995). To determine if
