During the past decade, research and practice in the field of behavior modification have experienced phenomenal growth. Behavioral inter vention strategies that were considered strictly experimental a few years ago are now accepted therapeutic modalities, and behavioral method ology has been instrumental in creating an atmosphere conducive to the development of scientific rigor in the area of mental health. But behav ioral influence has not been limited to mental health. There has been considerable impact in education, industry, government, and general health care. Although behavior modification has made a significant impact on psychology in general, there has been a noticeable lack of theorizing and empirical research on issues primarily related to black populations. In fact, the black community in general, and black psychologists in partic ular, often have viewed behavioral approaches with suspicion. We hope that the material presented in this volume will serve to clarify what the behavioral approach is and what it is not and that it will help to foster an understanding of the behavioral approach. Moreover, empirical data demonstrating the effectiveness of behavioral procedures with black populations are presented. It is our hope that the material will provide some insight into how behavioral theory, methodology, and therapeutic strategies can be used to the benefit of black mental health in particular and the overall psychological health of the black community in general.

Scientific work on mnemonics and imagery conducted in the 1960s and early 1970s was directed at testing enthusiastic claims of the efficacy of memory tech niques developed by the ancient Greeks and further refined in the popular litera ture by "professional" mnemonists. The early research on imagery and mnemonics confirmed many of these claims and also illuminated the limitations of some techniques (e. g. , bizarre imagery). As such, these seminal studies clearly were valuable in providing a solid data base and, perhaps as important, making imagery and mnemonics acceptable research areas for experimental psycholo gists and educators. After this initial surge of work, however, it seemed that sub sequent contributions met with the attitude that "mnemonic techniques and imagery help memory, what else is new?" This attitude was not completely justi fied, however, given the theoretical insights from the work of such imagery and mnemonics pioneers as Gorden Bower, Allan Paivio, and William Rohwer. In the 1980s this claim is completely unjustified. Research on mnemonics and imagery has grown in exciting ways. Researchers are tapping the area's theoretical potential, both in terms of extending basic memory theories to account for the robust effects produced by mnemonic techniques and in terms of using explanations of mnemonic effects to understand basic memory processes. Individual differences in the use of imagery and mnemonic encoding activities are also being explored. This research has provided valuable information for basic memory theories (e. g.

One Army Air Corps soldier's ordeals during World War II. Written in the personable voice of someone reflecting honestly on his life's journey, this autobiography is full of anecdotes of a Depression-era Montana boyhood and culminates with the author's training for service as a B-17 pilot and subsequent role as a flight instructor.

This paper combines pre-pandemic face-to-face survey data with follow up phone surveys collected in April-May 2020 to quantify the overall and differential impacts of COVID-19 on household food security, labor market participation and local food prices in Nigeria. We exploit spatial variation in exposure to COVID-19 related infections and lockdown measures along with temporal differences in our outcomes of interest using a difference-in-difference approach. We find that those households exposed to higher COVID-19 cases or mobility lockdowns experience a significant increase in measures of food insecurity. Examining possible transmission channels for this effect, we find that COVID-19 significantly reduces labor market participation and increases food prices. We find that impacts differ by economic activities and households. For instance, lockdown measures increased households' experience of food insecurity by 12 percentage points and reduced the probability of participation in non-farm business activities by 13 percentage points. These lockdown measures have smaller impacts on wage-related activities and farming activities. In terms of food security, households relying on non-farm businesses, poorer households, those with school-aged children, and those living in remote and conflicted-affected zones have experienced relatively larger deteriorations in food insecurity. These findings can help inform immediate and medium-term policy responses, including social protection policies aiming at ameliorating the impacts of the pandemic, as well as guide targeting strategies of governments and international donor agencies by identifying the most impacted sub-populations.
